Without marriage there will be no renunciation, Buddha would not have left the world - for what? His wife, Yashodhara, must have created the situation - Mahavira would not have escaped to the mountains. Without marriage there would have been no Buddha, no Mahavira. Just think: the history would have been very flat, without any salt, tasteless. Marriage keeps this whole "sorry-go-round" on and on. People call it "merry-go-round".
