3. It is not advisable to sit still after a meal;

In addition, the key to meditation is "quietness", which is a kind of exercise to treat "drowsiness" and "falling off". The so-called "sleepiness" is the sleepiness that keeps akathisia going; The so-called "rising gap" means that meditation is disturbed by imagination during meditation. Sitting still in a state of "groggy" and "falling" can only be a sitting posture at best, not sitting still. Meditation focuses on quality. Only when the seated person is neither "groggy" nor "unable to lift his head" can he feel the wonderful effect of "letting go of everything" in "quietness".
