among the Buddhists, is one form of entire self-control, or samadhi, which is "like a man .who rises from his seat and walks steadily for the space of a whole day; as when it is received the mind continues in one even frame, undisturbed and unshaken." To attain this calm self-possession, it is necessary for a man to be careful in seven matters-viz. his residence, the road he traverses, his conversation, his company, his food, the season, and the position of the body.
