Gīta Tātparya 2.30

The being is eternal because of the Lord, not because of his own capacity

देही कुतः अवध्यः? यस्मादयमीश्वरः सर्वस्य जीवस्य सूक्ष्मे स्थूले च देहे रक्षकत्वेन अवस्थितः अत एव अवध्यः। न स्वसामर्थ्यं कस्यापि।

dehī kutaḥ avadhyaḥ? yasmādayamīśvaraḥ sarvasya jīvasya sūkṣme sthūle ca dehe rakṣakatvena avasthitaḥ ata eva avadhyaḥ. na svasāmarthyaṃ kasyāpi.

[देही (dehī) - embodied; कुतः (kutaḥ) - how; अवध्यः (avadhyaḥ) - invulnerable; यस्मात् (yasmāt) - because; अयम् (ayam) - this; ईश्वरः (īśvaraḥ) - lord; सर्वस्य (sarvasya) - of all; जीवस्य (jīvasya) - of beings; सूक्ष्मे (sūkṣme) - in subtle; स्थूले (sthūle) - in gross; च (ca) - and; देहे (dehe) - in body; रक्षकत्वेन (rakṣakatvena) - as protector; अवस्थितः (avasthitaḥ) - situated; अतः (ataḥ) - therefore; एव (eva) - indeed; अवध्यः (avadhyaḥ) - invulnerable; न (na) - not; स्वसामर्थ्यम् (svasāmarthyam) - own power; कस्यापि (kasyāpi) - of anyone;]

(How can the embodied be invulnerable? Because this Lord resides as the protector within the subtle and gross bodies of all beings, thus indeed invulnerable. It is not by anyone's own power.)

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.

"द्रव्यं कर्म च कालश्च स्वभावो जीव एव च। यदनुग्रहतः सन्ति न सन्ति यदुपेक्षया॥"

-इति हि भागवते।

-iti hi bhāgavate।

[इति (iti) - thus; हि (hi) - indeed; भागवते (bhāgavate) - in the Bhāgavata;]

"तत्र तत्र स्थितो विष्णुः नित्यं रक्षति नित्यदा। अनित्यदैवानित्यं च नित्यानित्ये ततस्ततः। भावाभावनियन्ता हि तदेकः पुरुषोत्तमः॥"

"tatra tatra sthito viṣṇuḥ nityaṃ rakṣati nityadā। anityadaivānityaṃ ca nityānitye tatastataḥ। bhāvābhāvaniyantā hi tadekaḥ puruṣottamaḥ॥"
