Bhagavad Gita sings:
या निशा सर्वभूतानां तस्यां जागर्ति संयमी ।
यस्यां जाग्रति भूतानि सा निशा पश्यतो मुनेः ॥२- ६९॥
yā niśā sarvabhūtānām
tasyām jāgarti sanyamī,
yasyām jāgrati bhutāni
sā niśā paśyato muneḥ (69)
“The true worshipper (yogi) remains awake amidst what is night for all creatures, but the perishable and transient worldly pleasures amidst which all living creatures stay awake are like night for the sage who has perceived reality.”
The transcendental Spirit is like night for living beings because God can be neither seen nor comprehended by thought. So HE is like night, but it is in this night that the spiritually conscious man remains awake because he has seen the formless and known the incomprehensible.
The seeker finds access to God through control of senses, peace of mind, and meditation. That is why the perishable worldly pleasures for which living beings toil day after day is night for God’s true worshiper.
The sage alone, who beholds the individual Self and the Universal Self and is indifferent to desire, succeeds in his enterprise of God-realization. So he dwells in the world and is yet untouched by it.
Hence awakening is a stage when initially a seeker starts getting access in God for self realization and finally attains the ultimate bliss..
