The glory of friendship is not the outstretched hand, not the kindly smile, nor the joy of companionship; it is the spiritual inspiration that comes to one when you discover that someone else believes in you and is willing to trust you with a friendship.
What I know for sure is that if you can survive 11 days in cramped quarters with a friend and come out laughing, your friendship is the real deal. I know ours is.
When the only bond between close friends is attachment, then even a minor issue may cause one's projections to change. As soon as our projections change, the attachment disappears, because that attachment was based solely on projection and expectation. It is possible to have compassion without attachment, and similarly, to have anger without hatred.
As long as you are lucky, you will have many friends; if cloudy times appear, you will be alone. -Donec eris felix, multos numerabis amicos; tempora si fuerint nubila, solus eris
Genuine human friendship is on the basis of human affection, irrespective of your position. Therefore, the more you show concern about the welfare and rights of others, the more you are a genuine friend. The more you remain open and sincere, then ultimately more benefits will come to you. If you forget or do not bother about others, then eventually you will lose your own benefit.
