Atharva Veda brings out the importance of the fire ritual
(Agni Upasana). Fire has the power to purify, and several Vedic hymns describe
the role of Agnihotra (fire ceremony) in maintaining the balance in nature.
Analysis of the effect of fire in yajna’s shows how, on
becoming hot, the air expands and ascends upwards, together with various
materials and particles (derived from various herbs used in Yajna) and seeds
the clouds that are then more likely to descent to Earth in the form of rain.

Purva Mimamsa Dharma Shastra says that the use of four types
of aromatic herbs in yajna fire will be extremely beneficial for the
environment.
The seers of Yajur Veda declared that clouds are formed by
vegetation. This profound statement shows their understanding of the dynamic
process of the formation of vapors by transpiration in the plants. These
vapors, laden with molecules of water as well as volatile ingredients of
plants, come into contact with the passing winds, condense into clouds and fall
on earth as rain.
