Tenth, dwelling in the open ground. The Mahāprajñāpāramitopadeśa states: 'I observe that dwelling under a tree is no different from having half a house; the canopy provides cool shade and joy, which again gives rise to attachment. One then undertakes dwelling in the open ground, where sunlight shines everywhere and the air is bright and pure, making it easy to enter the emptiness samādhi.' The Ekottarika-āgama states: 'A bhikṣu understands that this body exists only through the harmony of causes and conditions: there are 660 bones, 99,000 pores, 500 blood vessels and 500 tendons, and 80,000 families of worms. One should constantly contemplate and train in this; it is called the supreme dharma of emptiness.' The Samantapāsādikā states: 'If one undertakes the superior dhūta practice, whether under a tree or in an open area, one may not even use a kaṣāya robe as a shelter, nor take monastic bedding to use outside. If one is able to protect it properly, even using a kaṣāya to cover it so it does not become damp, one is permitted to use and accept it. For the intermediate dhūta practitioner, one stays in the open ground when there is no rain, and under a roof when it rains, and is permitted to use monastic bedding.' The treatise states that there are ten benefits: 'First, one does not seek shelter under trees. Second, one remains far removed from notions of "mine". Third, there are no disputes or litigation. Fourth, if one departs elsewhere, there is no lingering attachment. Fifth, there is little frivolous amusement. Sixth, one can endure wind, rain, venomous vermin, cold, and heat. Seventh, one is not pierced by the thorns of sound. Eighth, one does not cause sentient beings to harbor anger. Ninth, oneself also has no sorrow or resentment. Tenth, one does not frequent noisy and crowded places.' When the Tathāgata relied on the Great Fear Forest, wind and rain surged together; by day he entered the forest, and by night he sat out in the open. Sometimes villagers put tree branches into his ears and nose, or soiled him with feces and urine, or scattered dirt over him, yet he never gave rise to any ill thought toward them, and so forth.
