There is nothing that is not sacred; nothing that is not spiritual practice. Hakuin, that wonderful eighteenth-century Zen master who restored the vitality of Zen in Japan, warned against the belief that Zen requires the forceful rejection of all worldly concerns. True Zen practice is carried on in the midst of activity. When we are cooking, we are in deep cooking samadhi (where the logical and analytical ability of the being becomes silent). When we are cleaning, we are in deep cleaning samadhi. This condition, samadhi, is not a vacancy, a stupor, a spaced-out state of mind. It is a deeply awake, alert, vividly present condition—and of course, it may be blissful. We may be so vividly awake we can hear the ash from the incense fall.
