Karma is the most widely accepted idea in all Indian thought. Practically, what does it mean for us? It means everything for us. From that stored karma, a little bit is released and activated to give us this particular life. We are not incarnations of God, so we reincarnate. That means we come again and again. This born-again and again is actually a limitation, a prison house.
