One thing we have to understand about compassion.
Compassion (how we understand and experience ) is a built-in component of consciousness.
Being Advait ( non-dual ) and having compassion for all are intertwined.
Reaching Advait and not experiencing compassion is not possible.
That kind of compassion is impossible in animals because they have not evolved to that level – like humans.
Having a love for their babies is, of course, a natural gift for being a mother – again, a great advantage of nature mainly meant to ensure the baby’s survival when it is so helpless.
