In the forest, no animals complain. They accept their place in the food chain and pecking order. They know that nothing is permanent. A predator in one context (snake chasing rat) is a prey in another context (hawk chasing snake). A dominant alpha must give way to a younger, stronger alpha, who invariably emerges eventually. Humans seek rules that establish a permanent world — hence the quest for the elixir of immortality (amrita) in the Puranas which creates Amravati of the devas.
