स एवमेतद्गायत्रं प्राणेषु प्रोतं वेदप्राणी भवति सर्वमायुरेति ज्योग्जीवतिमहान्प्रजया पशुभिर्भवति महान्कीर्त्यामहामना स्यात्तद्व्रतम् ॥ २ ॥
In plain words
He who knows this Gāyatrī as woven within the vital breaths becomes truly vital—meaning his senses remain unimpaired. He attains the full span of life, as the scripture says: 'A hundred years is the full life of man.' Radiant and vigorous, he lives long. He becomes great through his descendants and grand in renown. That he should be magnanimous and free from pettiness—this is the sacred vow of one who meditates upon the Gāyatrī.
Close to the Sanskrit
He, who thus knows this Gāyatrī woven in the vital breaths, becomes a possessor of breath, meaning he becomes one with unimpaired senses. He attains the full span of life, based on the Vedic text 'a hundred years is the full life of a person.' Shining brightly, he lives. He becomes great by progeny and others. And great by fame. This becomes the vow of the Gāyatrī meditator, which means that he should be magnanimous, with a non-petty mind.
