या निशा सर्वभूतानां तस्यां जागर्ति संयमी | यस्यां जाग्रति भूतानि सा निशा पश्यतो मुनेः
yā niśā sarvabhūtānāṃ tasyāṃ jāgarti saṃyamī . yasyāṃ jāgrati bhūtāni sā niśā paśyato muneḥ
凡眾生之夜，自制者於其中覺醒；眾生於其中覺醒者，乃見道牟尼之夜。
The self-restrained man keeps awake during that which is night for all creatures. That during which creatures keep awake, it is night to the seeing sage.
對於世俗之人而言為真實的，對聖者而言卻是幻象，反之亦然。聖者安住於真我之中，這對他而言是白晝。他對世俗現象毫無意識，這些對他而言如同黑夜。而普通人對其真實本性毫無意識，靈性生活對他而言是黑夜。他體驗著感官享樂的對象，這對他而言是白晝。真我對他而言是虛無。對於聖者而言，這個世界是虛無。世俗之人因缺乏真我知識而處於徹底的黑暗中。對他們而言的黑暗，對聖者而言卻是光明。真我（阿特曼或梵）對世俗之人而言是黑夜，但聖者卻完全清醒。他直接認知著至高實相，即光中之光。他充滿了光明與真我知識（阿特曼智）。
That which is real for the wordlyminded people is illusion for the sage? and vice versa. The sage lives in the Self. This is day for him. He is unconscious of the wordly phenomena. They are night for him? as it were. The ordinary man is unconscious of his real nature. Life in the spirit is night for him. He is experiencing the objects of sensual enjoyment. This is day for him. The Self is a nonentity for him For a sage this world is a nonentity.The wordlyminded people are in utter darkness as they have no knowledge of the Self. What is darkness for them is all light for the sage. The Self? Atman or Brahman is night for the worldlyminded persons. But the sage is fully awake. He is directly cognising the supreme Reality? the Light of lights. He is full of illumination and AtmaJnana or knowledge of the Self.
