B.G 4.05 and 06
śrībhagavānuvāca
bahūni mē vyatītāni janmāni tava cārjuna। tānyahaṁ vēda sarvāṇi na tvaṁ vēttha parantapa ॥5॥
The Supreme Lord said:
O Arjuna, you and I have passed through many lives. I know all of them, but you, O Subduer of enemies, are not acquainted with them.
ajō'pi sannavyayātmā bhūtānāmīśvarō'pi san। prakr̥tiṁ svāmadhiṣṭhāya sambhavāmyātmamāyayā ॥6॥
Though my body is imperishable and I am the supreme lord of all the beings, I re-manifest and seem to be born, having established myself in my own inherent nature with the delusional power I possess.
Gīta Tātparya 4.06
'ātmamāyayā' - on His own interest. 'prakr̥tiṁ svāmadhiṣṭhāya' - by His inherent nature He established Himself. Unlike verses 7.5 and 9.10, here word 'Prakrti' is used with word 'sva', and thus needs to be interpreted as 'inherent nature', and not as 'insentient'.
ātmamāyayā ātmēcchayā। prakr̥tiṁ svāmadhiṣṭhāya svabhāvam।
The word 'ātmamāyayā' means on His own interest. The usage 'prakr̥tiṁ svāmadhiṣṭhāya', means by His inherent nature he established Himself.
"dēvasyaiṣa svabhāvō'yam"
"This inherent nature is that of the Lord only."
ityādiśrutēśca। ata ēva svaśabdēna viśēṣaṇaṁ
- there are such Vedic testimonials as well. For this reason only, the word 'sva' has special meaning:
"prakr̥tiṁ svāmavaṣṭabhya"
"He Himself, having entered the 'Prakrti', i.e. governing deity of the insentient".
ityādiṣu।
-there are such testimonials as well.
"mayādhyakṣēṇa prakr̥tiḥ"
"The 'Prakrti', i.e. governing deity of insentient is supervised by Me." (Bhagavad Gita 9.10)
ityādiṣu tu na svaśabdaḥ।
At verse 9.10 of Bhagavad Gita, 'sva' word is not used, (hence, here the usage does not mean 'My own inherent nature').
"prakr̥tiṁ viddhi mē parām"
"Understand Prakrti to be superior energy of mine."(Bhagavad Gita 7.5)
ityādiṣu sambandhitvēna pratītēranyā।
In such cases, due to asociation, the word ('Prakrti') needs to be interpreted differently.
atra tu svaśabdaḥ svarūpavācī। svabhāva ityatrāpi svākhyō bhāvaḥ svabhāvaḥ। bhāvaśabdastu sambandhyāśaṅkānivr̥ttayē। svasvabhāva iti tu svasvarūpamitivadupacāratvāśaṅkāṁ nivartayati।
In the current context, the word 'sva' conveys 'inherent nature'. In the usage of word 'svabhava' in the current context, it is identified with 'self becoming' and thus means 'inherent nature'. Indeed, the word 'bhāva', i.e. becoming, is used to remove any doubt regarding its reference. The usage "One's own inherent nature", is similar to the usage "One's own form". This way, it dispels the doubt regarding its appropriateness.
"sraṣṭr̥tvādisvabhāvatvāt svēcchayā viṣṇuravyayaḥ। sr̥ṣṭyādikaṁ karōtyaddhā svayaṁ ca bahudhā bhavēt॥"
"The imperishable lord Vishnu, as per His independent will, by his inherent nature ('svabhāva'), undertakes creation and such activities. By such creation activities, He Himself becomes many."
iti nārāyaṇaśrutiḥ ॥6,7॥
- thus states Narayana Vedic testimonial.
Note:For grammatical clarification, it is necessary to refer to Gita Vivrutti of Sri Raghavendra Theertha, which is beyond the scope of current translation.
