Among Vedic Rishis, Bhardawaja Rishi lived through three lives, at the end of which he became immortal and ascended to the heavenly world, to union with the sun. Rishi Bharadawaj’s father was Guru Brahaspati and mother was Mamta. Lord Sri Rama had gone to his Asharam during ‘Forest life’. Rishi Bharadawaj’s hymns were collected in Rig-Veda and Atharveda. Rishi Bharadawaj’s work include “Bharadawaj-Smriti”, “Bharadawaj-Samhita”, and “Vimana-Shastra”. In “Vimana-Shastra” Bharadawaj Rishi wrote the details to build different types of aircrafts. It is very interesting fact that Rishis of India had known the technology to fly in air thousands year ago. In “Vimana-Shastra” Great Rishi Bharadwaja explained the construction of aircraft and way to fly it in air, on land, on water and use the same aircrat like a sub-marine. He also described the construction of war planes and fighter aircraft. Vaimaanikashastra explains the metals and alloys and other required material, which can be make an aircraft imperishable in any condition; but the technology available today does not allow us to create metal with some of the properties that are described.
The first principle of Vaimaanikashastra defines an aircraft.
“Vegasaamyaat Vaiaano Andajaanaam!”
Which means Vimaana is the one which can fly in air like a bird. Subsequent principles explain the requirements for being a Vimaanaadhikari or pilot.
In Jatyadhikarana, which classified aircraft says, “Jaatitrividaym Yugabhedath Vimaanaanaam!” The aircraft is classified into three types: Mantrika, Tantrika and Kritaka, to suit different yugas. In Kritayuga, it is said, Dharma was well established. The people of that time had the devinity to reach any place using their Ashtasiddhis. The aircraft used in Dwaparayuga were called Mantrikavimana, flown by the power of tantras. Fifty six varieties of aircraft including Bhairava and Nandaka belong to this era. The aircraft used in Kaliyuga, the ongoing yuga, are called Kritakavimana, flown by the power of engines. Twenty-five varieties of aircraft including Shakuna, Sundara and Rukmavimana belong to this era.
According to Bharadwaja, Angaanyekaatrishat, which means there were thirty-one instruments to fly an aircraft, including Vishwakriyaadarpana, to see the surroundings from the aircraft and Shaktyaa karshanadarpana, to absorb solar energy. Manufacture of different types of instruments and putting them together to form an aircraft are also described.
In Vastraadhikarana, the chapter describing the dress and other wear required while flying, talks in detail about the wear for both the pilot and the passenger separately.
Ahaaraadhikarana is yet another section exclusively dealing with the food habits of a pilot. This has a variety of guidelines for pilots to keep their health through strict diet.
According to Bharadwaja, there are 32 secret techniques to fly an aircraft. They are Maantrika, Taantrika, Taantrika, Kritaka, Antaraaia, Gooda, Drishya, Adrishya, Paroksha, Aparoksha, Sankoncha, Vistrita, Viropakarana, Roopantara, Suroopa, Jyotirbhava, Tamomaya, Pralaya, Vimikha, Taara, Mahashabada vimochana, Langhana, Saarpagamana, Chaapala, Sarvatomukha, Parashabda graahaka, Roopaakarshanam Kriyaa rahasya grahana, Dikpradarshana, Aakaashaakara rachana, Jaladaruja, Stabdaka and Karshana.
It is interesting to know that some enthusiats tried to show the knowledge of “Vimana-Shastra” and some tried to build aircraft also.
