When we look back on this life, we see that when people are born, no one has thoughts of joy, sadness, hatred, bitterness. Are we not born with the state of Buddha mind, given by our parents? But once intelligence develops, we learn habits from others, and the Buddha mind is turned into a monster because of self-importance. We argue, lose our temper muse over useless things, repeat the same thoughts again and again… It is darkness to darkness in an endless cycle.
