how is the life after family life must be led as per puranas in old age.

  The third ashrama is known as

vanaprastha (forest-dwelling stage). The individual now retires to the forest and withdraws his mind

from the earthly life. He can leave his wife in the care of his sons or take her with him. He lives on roots,

fruits and leaves and makes a bed for himself under the trees. He is not permitted to shave or cut his

hair and his clothes have to be made out of bark or skins. The final ashrama is that of sannyasa

(hermithood). A hermit gives up all association with the world and lives alone. He grows completely

detached. He lives alone. He gets his food through begging. He is not permitted to spend more than

one night in a village, or more than five nights at a time in a city.
