Nineteenth Kha\"N"D"A.
1. The hikra is hair, the prastva skin, the udgtha flesh, the pratihra bone, the nidhana marrow. That is the Ya"g"ya"g"ya Sman, as interwoven in the members of the body.
2. He who thus knows the Ya"g"ya"g"ya, as interwoven in the members of the body, becomes possessed of strong limbs, he is not crippled in any limb, he reaches the full life, he lives long, becomes great with children and cattle, great by fame. His rule is, 'Do not eat marrow for a year,' or 'Do not eat marrow at all.'
