In oneself lies the whole world and if you know how to look and learn, the door is there and the key is in your hand. Nobody on earth can give you either the key or the door to open, except yourself.
I believe all suffering is caused by ignorance. People inflict pain on others in the selfish pursuit of their happiness or satisfaction. Yet true happiness comes from a sense of inner peace and contentment, which in turn must be achieved through the cultivation of altruism, of love and compassion and elimination of ignorance, selfishness and greed.
