The room should have a small door, be free from holes, hollows, neither too high nor too low, well plastered with cowdung and free from dirt, filth and insects. On its outside there should be bowers, raised platform (chabootrâ), a well, and a compound. These characteristics of a room for Hatha Yogîs have been described by adepts in the practice of Hatha.
