Friends have been defined as people who know you at your worst and like you anyway, people in whose company you can be yourself. But perhaps more than anything else, friends are people who care about you for who you are, not what you can do for them. There is a kind of holiness in true friendship, because it makes sure that we are never alone when we desperately need to not be alone.
In a cave, all outer sounds are smothered by rock and earth, but this makes the sounds of one's own heartbeat and breath audible. In the same way, contemplative stillness turns us away from everyday clamor but allows us to hear the subtle in our own lives. When listening not with the ear but with the spirit, one can perceive the subtle sound. By entering into that sound, we enter into supreme purity. That is why so many religious traditions pray, sing, or chant as a prelude to silence. They understand that the repetition and absorption of sound leads to sacredness itself. The deepest sound is silence. This may seem paradoxical only if we regard silence as an absence of life and its opposites. It is both sound and soundlessness, and it is in this confluence that the power of meditation emerges.
