One writer refers to two kinds of friendship. One, called 'psychic' friendship, relies on the natural affinities, responses and capacities of those involved, including like-mindedness, attraction of opposites and shared interests. Affection found in 'psychic' friendship seeks immediate contact with the other person. The other kind is called 'spiritual' friendship, with spiritual interaction that depends on moral and spiritual principles that are not always fully appreciated. All friendships are a mixture of both kinds, but tend to belong more to one than another.
Sexual passion belongs within a mutual and healthy love relationship.
Lust, unrelated to care and commitment, generates enormous negative, destructive tension. Easy sexual relations of all kinds, instead of making supportive and intimate friendship more available, have helped destroy it, despite the longings people feel. Selfish love creates fear and builds barriers. Selfless love dissolves fear, creating space for security and fun. A giving friendship is good for all, bad for none, releasing people's potential, encouraging greatness and building confidence, like sunshine ripening fruit.
