One who is taking to the vānaprastha stage of life should leave his wife at home in the care of his sons, or else take her along, and with a peaceful mind spend the third quarter of his life in the forest. He should accept as his food whatever bulbs, fruits, roots and so on that grow in the forest, taking sometimes grains cooked by fire and sometimes fruits ripened by time. Furthermore, he should take as his garments tree bark, grass, leaves or the skin of a deer. It is prescribed that he should perform austerities by not cutting his hair, beard, or nails. Nor should he make any special attempt to remove dirt from his limbs. He should bathe three times daily in cold water and sleep upon the ground. During the hot season he should stand beneath the fearsome heat of the sun with fires blazing on four sides. During the rainy season he should stand in the midst of the downpour of rain, and during the cold winter he should submerge himself in water up to his neck. He is absolutely forbidden to clean his teeth, to store food that he has collected at one time to eat at another time, and to worship the Supreme Lord with the flesh of animals. If he can maintain those severe practices for the remainder of his life, the vānaprastha will achieve the Tapoloka planet.
