OSHO
Consciousness exists because of unconsciousness, the day exists because of the night, life exists because of death, happiness exists because of unhappiness, and so on and so forth. Everything exists because of its polar opposite. You cannot experience happiness unless you have deeply experienced unhappiness, and you cannot come to the ultimate ecstasy if you have not been thrown into ultimate agony. Hence the meaning of the world, hence this whole suffering. It is not meaningless. [OSHO]
