Naturally, we enter into meditation with some interest and enthusiasm, and there are goals to be attained. But in practice, we must drop these. We must avoid the distractions created by expectations and not be tempted into placing quantity — the number of sessions we do per day, the “higher, more esoteric” practices we know, or how many mantras we have recited — over quality. If we get in a rush, we are introducing the stress typical of samsara. Instead, we cultivate patience. Samadhi . . . will arise naturally when we relax beyond our desires, goals, and expectations.
