Child's wisdom cares not for anything and he passes his time in joyful activities.
In youthful days, he is attracted by other's body, wealth and backbiting.
In old age he is caught in the large web of family affairs.
Known to be seventy-two he becomes frail and wisdom less and mumbles in sleep.
Ultimately he turns blind, deaf and lame and though the body gets tired yet his mind runs in ten directions.
Without Holy Congregation and bereft of Guru-word he transmigrates into infinite species of life.
The time lost cannot be regained.(18)
