Question

What purpose does the vedas serve in Hinduism

Answer 1

The "vedas" are collections of poems, myths, and rituals. The vedas were written by aryan priests. This collection describes  daily life and religious beliefs associated with it.

Answer 2

Humanity is disturbing this natural condition on which his existence, along with the existence of all other forms of life, depends. This is like the action of a woodcutter cutting a tree at the trunk, on the branch on which he is sitting. According to Hindu religion, “dharanath dharma ucyate”—that which sustains all species of life and helps to maintain harmonious relationship among them is dharma. That which disturbs such ecology is adharma.
