Friend
A true friend is someone who does not help you to avoid your
loneliness but who helps you to deal with it. A real friend is
someone who actually makes it easier for you to be alone. A true
friend does not help you avoid feeling your aloneness, but helps
you to feel and accept your aloneness. In fact, a friend is someone
you can be really alone with more easily, in a sense, than in
an intimate relationship. (Diamond Heart Book 2, pg 179)

Leaving someone alone means not trying to manipulate them, not
trying to control them, not trying to make them one way or another,
not trying to make them respond in one way or another. When a
friend leaves you alone, that friend is with you as an emptiness,
in a sense, as an acceptance. (Diamond Heart Book 2, pg 180)

So a friend is there, is present, to help you understand, to
expose what is there in yourself and thus to understand what the
situation is, why you are behaving in certain ways and why the
situation is as it is. When you understand it, naturally you will
know what is the best thing to do. A friend does not give his
own opinion and experience, and impose it on you. A friend helps
you find your own solution. (Diamond Heart Book 2, pg 181)

Whenever there is a touching of truth in you, the friend is happy.
If you're hurting, a friend is compassionate, kind. If you happen
to be angry because you're hurting, a friend is even more compassionate.
The friend has no opinion about you. The friend has no prejudice
about you. The friend sees you just the way you are. So the friend
is completely objective, with no emotional bias of any sort. A
friend is someone who can see you exactly the way you are at the
moment and who is spacious enough and generous enough to allow
you to be just that. That's why people like friendship: the friend
is somebody with whom you can be yourself. (Diamond Heart Book
2, pg 182)
