* "The Upanishads, Part 1 (sbe01)\", by Max Mller, [1879],
Twelfth Kha\"N"D"A.
1. The hikra is, he rubs (the fire-stick); the prastva, smoke rises; the udgtha, it burns; the pratihra, there are glowing coals; the nidhana, it goes down; the nidhana, it is gone out. This is the Rathantara Sman as interwoven in fire 3.
2. He who thus knows this Rathantara interwoven in fire, becomes radiant 4 and strong. He reaches the full life, he lives long, becomes great with children and cattle, great by fame. The rule is, 'Do not rinse the mouth or spit before the fire.'
