B.G 2.72
ēṣā brāhmī sthitiḥ pārtha naināṁ prāpya vimuhyati। sthitvāsyāmantakālēpi brahma nirvāṇamr̥cchati ॥72॥
O Partha, on obtaining "brāhmī sthiti", the mind stationed on the topic of Brahman, one is not bewildered. If he continues to be stationed thus, even at the time of death, he attains a bodiless form similar to Brahman.
Gīta Tātparya 2.72
'brāhmī' - on the topic of Brahman. Even a Janānin, as per the rule, gets the remembrance of the lord while departing, only after the destruction of previous imprints. 'bāṇaṁ' - physical body.
brāhmī brahmaviṣayā। jñānināmapyantakālē anyamanasāṁ prārabdhakarmabhāvāt janmāntaram। prārabdha karmanāśakālē niyamēna bhagavatsmr̥'tirbhavati। tatō mōkṣaśca।
The word 'brāhmī' means 'on the topic of Brahman'. Even for a janānin, due to remaining imprints, mind goes after other topics at the time of death, and it results in rebirth. When the previous imprints are destroyed, as per the rule, he gets the remembrance of the lord while departing, and as a result gets liberated.
"yaṁ yaṁ vāpi smaran bhāvam"
"Whatever mental thought the departing person remembers..."
iti hi vakṣyati।
is stated thus in Bhagavad Gita itself, in 8.6 verse.
bāṇaṁ śarīram।
The word 'bāṇaṁ' means physical body.
"abhāvāt jaḍadēhasya viṣṇurnirvāṇa ucyatē। bhinnadēhābhāvatō vā sa sahasraśirā api॥"
"Vishnu is said to be 'nirvāṇa' as he is without a physical body. He is also called thousand headed as he is without differentiated body."
