OSHO: Nobody Teaches You About Hate:

Excerpts from an OSHO Talk
Love and Hate - Two Sides of the Same Coin

These are the ways they have spoiled your authenticity about love.
It is because nobody has been teaching you about hate; hence, hate has remained pure, unadulterated. Nobody has bothered about you, nobody has told you how to hate, whom to hate. Because hate has been left untouched by your parents, teachers, and priests, it has a purity, a sincerity. When a man hates you, you can trust that he hates you.
