Bhagavad-gītā As It Is · Text 8.20
Mortality, cosmic cycles and eternal destination
परस्तस्मात्तु भावोऽन्योऽव्यक्तोऽव्यक्तात्सनातन: ।
य: स सर्वेषु भूतेषु नश्यत्सु न विनश्यति ॥ २० ॥
paras tasmāt tu bhāvo ’nyo
’vyakto ’vyaktāt sanātanaḥ
yaḥ sa sarveṣu bhūteṣu
naśyatsu na vinaśyati
Yet there is another unmanifest nature, which is eternal and is transcendental to this manifested and unmanifested matter. It is supreme and is never annihilated. When all in this world is annihilated, that part remains as it is.
