या निशा सर्वभूतानां तस्यां जागर्ति संयमी। यस्यां जाग्रति भूतानि सा निशा पश्यतो मुनेः।।2.69।।
yā niśhā sarva-bhūtānāṁ tasyāṁ jāgarti sanyamī yasyāṁ jāgrati bhūtāni sā niśhā paśhyato muneḥ
That which is night to all beings, in that the self-controlled man is awake; when all beings are awake, that is night for the sage who sees.
