sarva-bhūtānām yā niśā–That which is night for all living beings (who, immersed in ignorance, remain asleep to spiritual knowledge); tasyām–in that night; saṁyamī–the self-disciplined person; jāgarti–remains awake (joyful in his spiritual intelligence). yasyām–That

(mundane intelligence) in which; bhūtāni–all living beings; jāgrati–remain awake (experience the pleasures and pains, sorrows and delusions of worldly life); sā–such (mundane intelligence) is; niśā–night; muneḥ–for the sage; paśyataḥ–who sees (the futility of mundane endeavours and remains indifferent to the dualities). [69]

That which is day for the self-controlled sage is night for all beings, and that which is day for all beings is night for the sage who sees. (The living beings absorbed in mundane life are asleep to the spiritual joy of the realised soul, who remains indifferent to their quest for the pleasures of the senses, devoid of spiritual joy.)
