Love and hate are both based upon self-identification in your experience. You do not bother to love or hate persons you cannot identify with at all. They leave you relatively untouched. They do not elicit deep emotion.

Hatred always involves a painful sense of separation from love, which may be idealized. A person you feel strongly against at any given time upsets you because he or she does not live up to your expectations. The higher your expectations the greater any divergence from them seems. If you hate a parent it is precisely because you expect such love. A person from whom you expect nothing will never earn your bitterness.

In a strange manner, then, hatred is a means of returning to love; and left alone and expressed it is meant to communicate a separation that exists in relation to what is expected.

Love, therefore, can contain hate very nicely. Hatred can contain love and be driven by it, particularly by an idealized love. (Pause.) You "hate" something that separates you from a loved object. It is precisely because the object is loved that it is so disliked if expectations are not met. You may love a parent, and if the parent does not seem to return the love and denies your expectations, then you may "hate" the same parent because of the love that leads you to expect more. The hatred is meant to get you your love back. It is supposed to lead to a communication from you, stating your feelings – clearing the air, so to speak, and bringing you closer to the love object. Hatred is not the denial of love, then, but an attempt to regain it, and a painful recognition of circumstances that separate you from it.

If you understood the nature of love you would be able to accept feelings of hatred. Affirmation can include the expression of such strong emotions.

How does it take me 40 years to find such a spot-on description? This should be taught in schools.
