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
众生皆睡的黑夜，自制者却清醒着；众生皆醒的时刻，在洞察的牟尼看来却是黑夜。
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.
对世俗之人而言是真实的事物，对圣者而言却是幻象；反之亦然。圣者活在神我之中，这对他而言是白昼。他对世俗现象毫无察觉，这些对他而言如同黑夜。普通人则对其真实本性一无所知，灵性生活对他而言是黑夜。他体验着感官享乐的对象，这对他而言是白昼。神我对他而言是虚无。对圣者而言，这个世界是虚无。世俗之人处于彻底的黑暗中，因为他们对神我一无所知。对他们而言是黑暗的，对圣者而言却是光明。神我、阿特曼或梵，对世俗之人而言是黑夜。但圣者却完全清醒。他直接认知至高无上的实相，那光中之光。他充满光明和阿特曼智识（对神我的认知）。
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.
