Man has to create marriage because man is afraid of the unknown. On all levels of life and existence, man has created substitutes: for love there is marriage; for real religion there are sects - they are like marriages. Hinduism, Mohammedanism, Christianity, Jainism - they are not real religion. Real religion has no name; it is like love. But because love is dangerous and you are so afraid of the future, you would like to have some security. You believe more in insurance companies than in life. That's why you have created marriage.
