Maharshi Bharadwaja is an august name in the pantheon of Hindu Sages who recorded Indian civilization, in the spiritual, intellectual, and scientific fields in the hoary past. The rishis transmitted knowledge from mouth to mouth and from ear to ear, for long eras. Written transmission through birch-backs or palm leaves or home made paper, are from this side of a thousand years. The word “yantra” is derived from the root yam, to control, and has been freely used in ancient India for any contrivance. Mechanical skills had produced in ancient India many accessories for scientific activities, such as surgical instruments in medicine, the pakayantras or laboratory equipment in medicine, Rasayana, and the astronomical yantras described in Jyotisa works. These belong to a different category. In the Mahabharata we hear of the Matsya-yantra or the revolving wheel with a fish which Arjuna had to shoot in order to win Draupadi in the svayamvara.
More interesting references are made by Valmiki to yantras on the field of battle, the continuity of which tradition we see later in the Arthasastra of Kautilya. The fortifications include equipment in the form of yantras. In Ayodhya 100.53, in the Kaccita-sarga, while enquiring about measures of defense, Rama asks Bharata whether the fort is equipped with yantras. Lanka, as a city built by Maya, is naturally more full of the yantras. The city, personified as a lady, is called yantra-agara-stani, informing us of a special chamber filled with yantras. (Sundara 3. 18). The Arthasastra of Kautilya is one of the books of culture which throws a flood of light on the particular epochs in which they arose. This work of 300 B.C.E. being a treatise on statecraft, speaks of yantras in connection mainly with battles, but also with architecture to some extent. An early work, a theoretical treatise and a text of great reputation, the Arthasastra forms our most valuable document on the subject of yantras.
And, as early as the Bhagavad Gita, the machine became an apt simile for man being a tool in the hands of the Almighty that sits in man's heart and by His mystic power makes man not only move but also delude himself into the notion of his being a free or competent agent.
“To deny to Babylon, to Egypt and to India, their part in the development of science and scientific thinking is to defy the testimony of the ancients, supported by the discovery of the modern authorities. - L. C. Karpinski
“Thus we see that India’s marvels were not always false.” - Lynn Thorndike.

There is the key in the center of the lotus. In it there are eight screws for the 8 petals. By working any screw the things that are in the connected petal will go high above and form a cloud. By working the central key fumes like solar rays will be given out. As soon as the heat of these fumes acts upon those clouds formed before, they begin to rain. This machine is specialized to get rain.
Souryayana Yantram
This is like a pillar 116 feet high and 58 feet in circumference. At the top there is a sieve containing holes and made of glass of the 96th class called Somapa. From this sieve in this pillar there are twelve machines in order. Above the sieve there is a covering of 97th class of glass called Somasya Darpana. Above this covering there is a glass wheel called Kumudinee containing spokes made of 98th class of glass called Chandrika Darpana. In the twelve points of this machine there are twelve upper screws and twelve lower screws. Bu turning the first screw, the contents of the machine such as electricity, cold fluid, Shaitya Drava, Sudha Mushee, Soonruta, Pushkalee, Pranada, Dravinaamrutha, Sooraneee, Jambaalee, Lulita, Vaachaklavee, Gacyoosha, rise up in the definite proportions. Through the cylindrical tubes which are fixed to the wheels of the sieve these powers pass and touch the glass covering above. By turning the electric screw then, the wheel turns 1192 rounds in a minute. Then a power called Someeya of the lunar rays is attracted by this wheel and it gets down through the sieve. Thus the power fills in the bottle below in the form of gas. It must be kept air-tight. Its use is this. When such limbs as head, hands, feet, of a person are cut off, the limbs are fixed to the right place of the body and the body kept in a box. The body must be wrapped in a covering of the bark of a plant called Vaarshneeka Valkala. When to such a body the above Somadrava gas is injuncted 5 Rajanikas, the body is resuscitated. This must be done within five minutes after the injury is done. Used in setting the cut limbs right, or resuscitating the persons killed, in the above manner.
