The hiṅkâra is hair, the prastâva skin, the udgîtha flesh, the pratihâra bone, the nidhana marrow. That is the Yagñâyagñîya Sâman, as interwoven in the members of the body.

He who thus knows the Yagñâyagñîya, 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.'
