Friendship is a relationship. You can be in that relationship with a
few people. Friendliness is a quality not a relationship. It has
nothing to do with anybody else, it is basically your inner quality.
You can be friendly even when you are alone. You cannot be in
friendship when you are alone - the other is needed - but
friendliness is a kind of fragrance. A flower opens in the jungle;
nobody passes by - still it is fragrant. It does not matter whether
anybody comes to know of it or not, it is its quality. Nobody may
ever come to know about it, but that does not matter; it is
rejoicing.
Friendship can exist only between one man and another man or at the
most between a man and an animal - a horse, a dog. But friendliness
can exist even with a rock, with a river, with a mountain, with a
cloud, with a far-away star. Friendliness is unlimited because it is
not dependent on the other; absolutely your own flowering.
