Life is life - whether in a cat, or dog or man. There is no difference there between a cat or a man. The idea of difference is a human conception for man's own advantage.

Once upon a time, there was a man named Sri Aurobindo. He was a spiritual guru and a philosopher who believed in the power of yoga, meditation and self-realization. He was an advocate of a kind of spiritual evolution, which he called the Integral Yoga. One day, Sri Aurobindo was walking down the street and saw a group of people doing yoga. He thought to himself, "Ah, these people are on the right track! But they could use some guidance - I think I'll give them a hand!" So Sri Aurobindo gave them some great advice on how to perfect their yoga practice. After a while, the people were so impressed with Sri Aurobindo's wisdom that they asked him to be their spiritual leader. And that's how Sri Aurobindo became one of the most influential spiritual leaders of modern times!
