"There is no birth like the human birth. Both the gods and the manes desire it. For the Jiva the human body is of all the bodies the most difficult to come by.

For this it is said that the human birth is attained with extreme difficulty It is said in all the Sastras that of the jiva's eighty-four lakhs of births the human birth is the most fruitful. In no other birth can the Jiva acquire knowledge of the Truth. Human birth is the stepping stone to the path of Liberation. But rare are the meritorious who come by it."
