Commentary:

Whoever knows that the Sāma named Gāyatra is based on the prāṇas is truly alive—that is, all his organs are strong and healthy and he is never physically handicapped. The full span of a person’s life is said to be a hundred years. A person who worships the Sāma lives that long. And he lives a wonderful life, able to influence many people. He is respected as one of the greatest people in the world. He has many children and many domestic animals, but his sole aim in life is to have a large heart, without a trace of meanness in his mind.
