Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The vanaprastha should wear matted locks of hair on his head and let his body hair, nails and moustache grow. He should not cleanse his body of dirt. He should keep a waterpot, deerskin and rod, wear the bark of a tree as a covering, and use garments colored like fire.
