Dr. V. Ganapati Sthapati

A Short Biography

Born in the year 1927, at Pillayarpatti, a village near Karaikudi, Tamilnadu, Dr. V. Ganapati Sthapati comes from an illustrious family of temple architects and sculptors. His family lineage stretches back over one hundred decades including the sthapatis who created the great Brihadeeswara Temple of Tanjore, the treasure house of Indian art and architecture. Son of Sri Vaidyanatha Sthapati, a renowned sculptor and Sanskrit scholar, he has made remarkable contributions to the field of art and architecture.

As the Doyen of Indian Vaastu Shastra (recently given the title of “Shilpi Guru” by the President of India) he has been doing research in the field of Vaastu Science and Technology for the past 50 years. A graduate in Mathematics and Sanskrit, Sthapati is propagating this supreme science in India and abroad. He is solely responsible for the resurrection of the works of the Great Brahmarishi Mayan, who was the progenitor of this Indian science and technology and the founder of this rich civilization and culture.

As the Principal of the Government College of Architecture and Sculpture (the only institute of this kind in the world) at Mamallapuram, near Chennai, for 27 years, Sthapati worked hard to restore and elevate the status of the sacred art and architecture by affiliating courses to the University of Madras and offering degree courses. This brought academic status to the age-old tradition of learning and also initiated many young people into this traditional technology.

After retirement from government service, he established Vaastu Vedic Trust and Vaastu Vedic Research Foundation aimed at research, development and globalization of Vaastu Shastra. He is also the head of the professional guild named V. Ganapati Sthapati & Associates. This group of talented designers, engineers and craftsmen work together to create Vaastu inspired temples and other buildings in India and abroad. The palatial buildings of library and administrative block for Tamil University of Tanjore and the Muthiah Mandram in Madurai speak of his capacity for designing and executing works of stupendous nature. Of particular interest is his monumental vaastu sculpture/building of Thiruvalluvar at the southern tip of India at Kanya Kumari measuring 133 feet in elevation: a stone statue of liberty for India. This colossal marvel has taken him to the pinnacle of his life’s achievement as a traditional architect and builder and commendations and awards have reached him from around the world for this achievement: a poetic image that will be with us for thousands of years.

He has authored a number of books on the science and technology of Vastu Shastra and has conducted numerous seminars with professionals in a generous effort to make this knowledge available to the world. He has established the International Institute of Mayonic Science and Technology, which conducts workshops and discourses all over the world.

Sthapati holds the post of the Professor and the Head of the Department of Sthapatya Veda in the World University of Traditional Indian Science, Technology and Culture in Chennai.

Some of the notable books he has authored include: Iconometry, Temples of Space Science, The Building Architecture of Sthapatya Veda, and Commentary on Mayan’s Aintiram.

Sthapati has earned a number of titles and awards including an Honorary Fellowship by the Indian Institute of Architects, the National award for Master Craftsmanship by the President of India, the title of “Shilpi Guru of India” also by the President and a Doctorate Degree conferred by the Maharishi Mahesh Yogi Vedic University.

He has worked and researched the USA, U.K., Australia, France, Fiji, Germany, Holland, Singapore, Malaysia, Mexico, Guatemala and Peru.

This pulsating and vibrant researcher, sculptor, architect, philosopher and scientist has given forth many startling research discoveries on the intricacies of the traditional art and architecture of India and is quite optimistic that one day Vaastu science will be a major influence in the world. He has identified the theories of the origin of the Universe and its life forms through his research on the works of Mayan scaling height far beyond the mundane world of modern science and technology.

It is with deep gratitude that I introduce you to this great and generous man.

Our Mission

Our mission is to promote Vaastu Shastra and educate designers, architects, builders and homeowners of the potential of a more comfortable, happy and successful life lived in harmony through the principles of Vastu Shastra.

Michael Borden’s largest obstacle to learning this ancient science lay in finding a way to learn about it. When he began his search he quickly realized that the only reputable source of knowledge lay in going to India and studying there with a master. He studied the science of Vastu Architecture in India with Dr. V. Ganapati Sthapati, one of India’s most renowned temple architects, and has built structures according to these principles. With Dr. Sthapati’s guidance, he has structured an online seminar to make this knowledge easily available to all.

Through our online store we’ll endeavor to provide the very best products to the professional, the student, and the homeowner.

Vastu Architects – Associates

S. Santhana Krishnan Sthapati

StapatiEldest son of Shilparatnam. Sri. S. Shanmugam Sthapati, Sthapati Santhana Krishnan follows the footsteps of his father and continues to be a Temple Architect. Sri. S. Shanmugam Sthapati is a well experienced Temple architect who has been with Dr. Ganapati Sthapati since the age of six. He was the chief executive sthapati for Dr. Sthapati’s prestigious projects Saint Thiruvalluvar statue, 133’0 ht. granite stone structure that withstood the Tsunamic waves in 2004, Kanyakumari and Sanmarga Iraivan Temple, Kauai, USA. He has constructed number of Temples in India and abroad.

StapatiSthapati Santhana Krishnan completed his Bachelor’s degree in Temple Architecture from The college of Architecture and Sculpture, Mamallapuram in the year 1998 after which his interests deepened in exploring the intricate science of Sthapatya Veda. For which he studied M.A., M.Phil in Sanskrit Language from Ramakrishna Mission Vivekananda College, Chennai. Dr. Sthapati appointed him in his office while he was in college, which helped Santhana Krishnan gain practical experience at an early stage. Being associated with Shilpguru Dr.V.Ganapati Sthapati, Santhana Krishnan’s research activities in the ancient Texts of Ainthiram and Pranava Vedam widened.

He began to assist Dr. Sthapati in his research works and has presented papers related to Ainthiram. Evidences of information from MAYAN’s Ainthiram and Pranava Vedam were explored and identified in Tholkaapiyar’s Tholkappiyam, Thirumoolar’s Thirumandiram and Ramalinga Adigalaar’s Thiruvarutpa by Sthapati Santhana Krishnan, which gained appreciation among scholars. His search for more knowledge on Mayonic science continues. His research works include the studies of 108 Upanishads wherein he has found references relevant to Vastu shastra. He is presently translating Mayan’s Pranava Veda from Tamil to English. He has assisted Dr. Sthapati in conducting Vastu classes for International Institute of Mayonic Science and Technology, Chennai and American University of Mayonic Science and Technology, USA and is a Faculty for AUM. He is also a good speaker and has delivered speeches in number of conferences along with Dr. Sthapati.

StapatiSthapati Santhana Krishnan’s contribution to the Mayonic architecture under the guidance of Dr. Sthapati is awe inspiring. His primary focus is on Stone architecture and his first field experience began in the stone marking of 10 elephants for the illustrious project of Dr. Sthapati – SainSaint Thiruvalluvar Statue which stands in the midst of sea in Kanyakumari. He worked extensively on this project and other large temples in India and Sri Lanka. His one of the major projects is the Gurunathar Temple at Reddiapatti, south of Tamilnadu which is again a stone temple renovation project that was primarily constructed in cement and steel by Dr.V.Ganapati Sthapati. After seven years of intense work, this temple was consecrated in April 2007. This project has awarded the title of Sirpa Kalai Arasan for Sthapati Santhana Krishnan for his tremendous contribution in the making of this massive temple in stone. Sthapati. Out of his love for Mayonic Science, Sthapati Santhana Krishnan prefers to call himself as Sthapati Daasan as Kaalidaasan and Bharatidaasan

StapatiKrithika Karuppiah

A contemporary architect whose interest in the Traditional Indian architecture developed gradually during her periodical visits with Dr.V.Ganapati Sthapati, while receiving the guidance for her final year thesis project – Vedic Village (a topic that focused upon the application of Traditional Sthapatya Vedic principles in designing of buildings that will be suitable for today’s life style). After completion of Bachelor’s Degree of Architecture from Hindustan College of Engineering Madras University in the academic year 1999, Ms. Krithika decided to learn more on Sthapatya Veda and joined as an Architect in Dr. Sthapati’s organization. She has designed a number of Vaastu buildings like residences, schools, hospitals, factories, Religious and Monumental buildings, etc. under the tutelage of Dr. Sthapati for 9 years. By blending traditional vaastu grammar with modern space concepts, Krithika has been successful in creating magnificent structures that are spiritually and physically appeasing. Her first residential project in Chennai, Mr. Santhanam’s residence was designed as a pure Vaastu building. This project brought her into limelight when Dr. Sthapati, the client and herself were interviewed by the Discovery Channel team and telecast on Asian Enigma series.

During her career as a Sthapatya Vedic architect in Trinidad & Tobago, she along with her husband has designed remarkable projects thereby exposing Trinidadians to this wonderful Science of Sthapatya Veda. Her vaastu consultation services are spread worldwide.

StapatiMs. Krithika assists Dr. Sthapati in his research works and her illustrations appear in most of the books authored by Dr. Sthapati. She has delivered lectures along with Dr. Sthapati for foreign delegates during the annual workshops on Sthapatya Veda conducted by International Institute of Mayonic Science and Technolgy Chennai and American University of Mayonic Science and Technology USA. She is a Board member in the American university of Mayonic Science and Technology USA. Her interests in Mayonic Science have inspired her to assist her husband Sthapati S. Santhana Krishnan in the translation of Pranava Veda. She has presented papers on the Application of Sthapatya Vedic principles in Anna University Chennai.

General Vastu Questions

Over the past few years Vastu shastra has become a very popular phrase, what are the sustainability principles behind it?

Vastu shastra recommends the use of natural materials. My teacher, Dr. V. Ganpati Sthapati in Chennai said the best materials are “mother’s” That is Mother Earth: Earth, stone, wood. These materials are most resonant with Earth energy, most compatable. The space will have the most silence. Also, Vastu Science offers a kind of deep ecology because we are building a structure that has the mathematics to vibrate in harmony with Earth and Cosmic energy structures.

Vastu shastra is originated in India. Are people abroad showing interest in following it?

There is a great and growing interest from Indians in the west and from people open to new ideas in creating a harmonious home. I receive 1000’s of inquiries from all over the world each year.

Do you feel that modern architects are beginning to incorporate elements of this sacred architecture into their work?

Not so much, but there is evidence of these principles being used in most of the classical western architecture. Also there is much evidence of its use in ancient traditional cultures in the west. Modern architects tend to put the ego first. In other words, they use small self, personal decisions in creating the structure. Vaastu architecture design uses laws of nature type thinking to create a building.

What kinds of materials are used for Sustainable Architecture according to Vastu Shastra? Organic?

Vastu shastra recommends the use of natural materials.

Is nature an important part of Vastu and why?

Nature is the only part of vaastu. It creates a structure that has deep harmonious resonance with nature. This is why the buildings promote peace and prosperity.

Why is Vastu called the science of time and space? Why are the timing, direction and position of a home so important?

Time and space are the two basic ingredients in creation. The vastu architect is a master of the laws of time and space. Using these laws to create a structure that is basically the embodiment of time-space reality.

What are the rules of orientation as prescribed by Vastu texts pertaining to sustainability?

The basic rule is to create a structure that vibrates with universal energy and all the little sustainable issues are taken care of.
