After watching yaron brook discussion with the caller. I thought about what was said by yaron. Pain and suffering perhaps make you understand better about joy and pleasure. Same can be said about joy and pleasure. Joy and pleasure makes you stronger because you know after pain and suffering you get back to joy and pleasure. Lets say about the this situation. Before you were joyful and happy. Then a cockroach came along. You are really afraid of cockroaches. So you get pain and suffering. But you know you can get back to your joyful and happy self after you disposed of it.
