Know that you and I are one. You can realize this only by intense spiritual discipline, that is not marred by anger, envy and greed...the vices that sprout from the ego. When you get angry, you act as if you are possessed by an evil spirit. Your face becomes ugly and frightful.  Heed that signal, and take yourself to a quiet spot.  Do not give free vent to wicked vocabulary. Envy and greed also emanate from the ego and have to be carefully watched and controlled. Like the tadpole's tail, the ego will fall away when one grows in wisdom. Develop wisdom, discriminate and know the ephemeral nature of all objective things.

- Sathya Sai Speaks,  Vol 5, Ch 1, Jan 14 1965. 

"Remove the roots of egoism from the field of your heart. That alone is sufficient to reach me." - Baba
