It is Child’s nature(स्वभाव) to be dependent for initial years of the life.
It is parasite’s nature(स्वभाव) to rely on a host (another animal or plant) for livelihood.
It is Gau’s nature to live and support humans.

Due to this innate nature or स्वभाव of an organism, symbiotic relations emerge among living beings.

I feel strange when I hear Utopian sentiments to free all domestic animals in jungles in name of reducing animal cruelty. At the same time, I feel frustrating when I see domestic animals are tortured for greed.

Ideal way is to respect the स्वभाव of each other and maintain symbiotic relations.
