Whatever the optimal time of day is for you, you should devote it to the cultivation of Tao. For example, dawn, when it is quiet, the world is fresh, and the mind is untainted by the day's events, is an ideal time to devote yourself to study. Morning, the time of birth, should not be wasted on a quick breakfast, a hastily read newspaper, and a manic rush to work. If is far better to awake from peaceful sleep, wash yourself, drink clear water, and immerse yourself in the rising energy of the day.

If your optimal time is evening, there are two propitious intervals : twilight, when day and night come into balance, and midnight, when the first breath of the coming day arises. In the night, worldly cares are put aside, rest and relaxation are paramount, and the entire world withdraws into nocturne. Night is the time of regeneration, and it should not be wasted on wanton entertainment, indulgent sexuality, and too much sleep. It is far better to retire from the cares of the day, bathe, and immerse yourself in the gestating power of the dark.
