The Manifestation and Naming of Rudra / Nīlalohita
शश्वच्च जायते यस्माच्छश्वत्संतिष्ठते तु यत् / तस्मात्मूर्यं न वीक्षेत आयुष्कामः शुचिः सदा
śaśvacca jāyate yasmācchaśvatsaṃtiṣṭhate tu yat / tasmātmūryaṃ na vīkṣeta āyuṣkāmaḥ śuciḥ sadā
For from Him there is ceaseless arising, and in Him there is ceaseless abiding; therefore the ever-pure seeker of long life should not gaze at the Sun when it stands above the head.
