The hiṅkâra is mind, the prastâva speech, the udgîtha sight, the pratihâra hearing, the nidhana breath. That is the Gâyatra Sâman, as interwoven in the (five) prânas.
He who thus knows this Gâyatra interwoven in the prânas, keeps his senses, reaches the full life, he lives long, becomes great with children and cattle, great by fame. The rule of him who thus meditates on the Gâyatra is, 'Be not high-minded.'
