सूर्याचन्द्रमसौ शश्वदंशुभिः केशसंज्ञितैः ।बोधयन्स्वापयंश्चैव जगदुत्तिष्ठते पृथक् ॥
In plain words
Sun and moon, endlessly, with the rays that go by the name keśa — waking the world, and laying it down to sleep again — each of them rises in its own turn.
Close to the Sanskrit
The sun and the moon, perpetually, by rays designated 'keśa', awakening and also putting to sleep the world, rise up separately.
