Through holiness and virtue alone men can go to the regions of bliss and their vows and fasts can become efficacious. Living on fruits and roots, observing the vow of silence, living on air, shaving one's head, abandoning a fixed home, having matted locks on head, lying under the sky, observing daily fasts, worshipping the fire, bathing in water and lying on the ground, these alone cannot lead one to heaven.
