Verse 221

ता वा अस्यैता हिता नाम नाड्योयथा केशः सहस्रधा भिन्नस्तावताऽणिम्नातिष्ठन्ति शुक्लस्य नीलस्य, पिङ्गलस्य हरि-तस्य लोहितस्य पूर्णा अथ यत्रैनं घ्नन्तीवजिनन्तीव हस्तीव विच्छाययति गर्तमिवपतति यदेव जाग्रद्भयं पश्यति तदत्रा-विद्यया मन्यतेऽथ यत्र देव इव राजेवाह-मेवेदं सर्वोऽस्मीति मन्यते सोऽस्य पर-मो लोकः ॥ २० ॥

In plain words

These are called his hitā channels — fine as a single hair split into a thousand strands, and running full with white, deep blue, tawny, green, and red. Now, there are times when something seems to strike him, seems to overpower him, when it feels like an elephant bearing down on him, when the light seems to drain out of things, when he feels himself falling into a pit — but whatever fear he has ever seen while awake, here he is only imagining it, out of nescience. And there are other times when, like a god, like a king, he feels 'I alone am all this' — and that is his highest world.

Close to the Sanskrit

These, indeed, are his channels called hitā, as fine as a hair split a thousandfold, standing full of white, dark blue, tawny, green, and red. Now, where, as it were, they strike him, as it were they overpower him, as it were an elephant, he is overshadowed, as it were he falls into a pit — that very fear which he sees while waking, that here he imagines through nescience. Now, where, as it were a god, as it were a king, 'I alone am all this' he thinks — that is his highest world. || 20 ||
