या निशा सर्वभूतानां तस्यां जागर्ति संयमी।
यस्यां जाग्रति भूतानि सा निशा पश्यतो मुनेः।।2.69।।
2.69 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.
2.69 That Buddhi (understanding) which has the self for its object, is night to all beings, i.e., is obscure like night to all. But he, who has subdued the senses and is serene, is awake in respect of the self. The meaning is that he has the vision of the self. All beings are awake, i.e., are actively cognisant in respect of objects of the senses like sound. But such sense objects are like things enshrouded by night to the sage who is awake to the self.
