B.G 2.30
dehī nityamavadhyo'yaṁ dehe sarvasya bhārata। tasmāt sarvāṇi bhūtāni na tvaṁ śocitumarhasi ॥2-30॥
O Bharata, this embodied being stationed in this body, is everlasting and indestructible everywhere. Therefore, you should not grieve for any creature.
Gīta Tātparya 2.30
The being is eternal because of the Lord, not because of his own capacity
dehī kutaḥ avadhyaḥ? yasmādayamīśvaraḥ sarvasya jīvasya sūkṣme sthūle ca dehe rakṣakatvena avasthitaḥ ata eva avadhyaḥ। na svasāmarthyaṁ kasyāpi।
How is the embodied indestructible? The Lord of all beings stations Himself as the protector of the subtle and gross bodies. Hence, it is indestructible, not because of its own strength at any given time.
"dravyaṁ karma ca kālaśca svabhāvo jīva eva ca। yadanugrahataḥ santi na santi yadupekṣayā॥"
-iti hi bhāgavate।
"The substance, the movement, the time; the essential nature, the being - all these exist because of his grace and cease to exist if he shows reluctance."
-states Bhagavata
"tatra tatra sthito viṣṇuḥ nityaṁ rakṣati nityadā।anityadaivānityaṁ ca nityānitye tatastataḥ। bhāvābhāvaniyantā hi tadekaḥ puruṣottamaḥ॥"
-iti pādme।
"Lord Vishnu stations himself there and there, and protects the eternals as eternal. Similarly, He keeps the non-eternal entities as non eternal. Thus, eternal and non-eternals come into being. As he controls the existent and non-existent, he is called best among the beings."
- thus states Padma Purāna
