Question: If world-perfection comes from the perfection of the individual souls, how will the animals ever become perfect?Sri Chinmoy: The world is evolving and progressing. Once upon a time we were all animals, but from the animal kingdom we entered into the human kingdom. Human beings are more perfect than animals, although we are still half-animals. But one day we will become perfect. Likewise, those souls still in the animal kingdom will also someday take human incarnation, and eventually perfection will dawn for them, too.
