All the Devataas (environmental powers) of Hindu mythology are broadly classified into five groups, popularly known as Pancha Devataa; the single iconic representative of each group are Ganesh, Soorya, Vishnu, Ssiva and Durgaa.

The concept of Pancha Yajnya (five scarifies), reflected in Manusmruti such as Rrushi Yajnya (Sacrifices: for the source of Knowledge -Teacher), Deva Yajnya (to the Gods – Environmental powers), Bhoota Yajnya (living creatures), Nrru Yajnya (to men) and Pitru Yajnya (to manes); is aimed to raise eco-consciousness amongst the human environment. Man, should be committed to show obligation to the above environmental agents as an ethical and ecological responsibility, from whom he receives unasked gifts continuously; is the basic theme of Pancha Yajnya; discussed in this communication from ethnobiological point of view.
