यदिच्छन्तो ब्रह्मचर्यं चरन्ति तत्ते पदं संग्रहेण प्रवक्ष्ये ॥रसोऽहमप्सु कौन्तेय प्रभास्मि शशिसूर्ययोः ।प्रणवः सर्ववेदेषु शब्दः खे पौरुषं नृषु ॥....................गिरामस्म्येकमक्षरम् ॥
In plain words
The thing they want when they take up brahmacarya and live it out — that state is what I will now tell you, gathered into a few words. I am the taste in water, Arjuna. I am the light in the moon and the sun. I am OM in all the Vedas, sound in space, the strength in human beings. ... Of all speech I am the one imperishable syllable.

That, desiring which they practise brahmacarya — that state I shall declare to you in brief. I am the taste in the waters, O son of Kuntī; I am the radiance in moon and sun; the praṇava in all the Vedas, sound in space, manliness in men. ... Of utterances I am the one imperishable syllable.
