Faith is taking the first step even when you can't see the whole staircase.
When we seek happiness through accumulation, either outside of ourselves--from other people, relationships, or material goods--or from our own self-development, we are missing the essential point. In either case we are trying to find completion. But according to Buddhism, such a strategy is doomed. Completion comes not from adding another piece to ourselves but from surrendering our ideas of perfection.
When you dwell in stillness, the judging mind can come through like a foghorn. "I don't like the pain in my knee...This is boring...I like this feeling of stillness; I had a good meditation yesterday, but today I'm having a bad meditation...It's not working for me. I'm no good at this. I'm no good, period..." This type of thinking dominates the mind and weighs it down. It's like carrying around a suitcase full of rocks on your head. It feels good to put it down. Imagine how it might feel to suspend all your judging and instead to let each moment be just as it is, without attempting to evaluate it as "good" or "bad." This would be a true stillness, a true liberation. Meditation means cultivating a non-judging attitude toward what comes up in the mind, come what may.
