Food is the basic requirement of every living being on earth and our ancient texts have proclaimed that even devatas relay on food, which is offered sacredly in the form of havis. <blockquote>अन्नाद्भवन्ति भूतानि पर्जन्यादन्नसंभवः । यज्ञाद्भवति पर्जन्यो यज्ञः कर्मसमुद्भवः ॥ (Bhag. Gita. 3.14)</blockquote>All creatures (life) comes into being from Anna (food), and this food arises with the help of rain. Through yajnas we get rain, thus yajna gives rise to activity or karma.

=== Prediction of Rainfall ===
=== Prediction of Rainfall ===
The systematic study of meteorological science was made by our ancient astronomers and astrologers. Agriculture is totally dependent on rainfall. This fact was first realised by Indians. Hence they started gauging the sky for rainfall prediction. Parashra gave the techniques of rainfall prediction and agricultural practices for crop production. Garg invented the science of astrology. Arybhata measured the time period of different planets and distance from earth. Varahmihira (600 AD) studied weather prediction and measurement of rainfall, touching zenith in the meteorological science. The hypotheses given by ancient scientists are simple and costly apparatus were not used. Observations coupled with experience over centuries developed meteorology (Varshney, 2007).
