The flow of meditation culminates in dhyana and it may culminate in samadhi. Nothing in this world, nothing in this world can match that joy. But again, note, it is still a joy which comes and goes. Only thing is difficult to achieve and hold on. That's why so few people know about it. At first it's hard work, but afterwards when you get into the flow, it's very sweet,. It's very nourishing, it's immensely attractive.
