That statement that faith rests on a belief that when the Buddha said, "All beings are equally endowed with this enlightened nature," that he was neither mistaken nor lying, is that faith required, really, to persevere in practice? I'd say no. Maybe if our aspiration is to awaken, maybe that can be very important. But in practical terms, that is, in terms of practice, the most basic faith is faith in the practice, the breath, the koan, whatever it is we're doing as our meditation practice. That's what it really comes down to, isn't it? And faith that by doing that particular method that we work on, in doing that, we benefit from it.
