You are asking, 'Is the concept of soul mates more useful than marriage?' Concepts don't matter. What matters is your understanding. You can change the word marriage to the word soul mates, but you are the same. You will make the same hell out of soul mates as you have been making out of marriage - nothing has changed, only the word, the label. Don't believe in labels too much.
RajneeshThis is a very fundamental reason why man cannot become meditative - or why very few men have dared to become meditative. Our training is of the mind. Our education is for the mind. Our ambitions, our desires, can only be fulfilled by the mind. You can become president of a country, prime minister, not by being meditative but by cultivating a very cunning mind. The whole education is geared by your parents, by your society, so that you can fulfill your desires, your ambitions. You want to become somebody. Meditation can only make you a nobody.
RajneeshMove inwards! Contentment is a quality of your center; it is not found on the circumference. Fulfillment is when you have arrived at your real, authentic being; it is not found in the ego.
