B.G 2.72
एषा ब्राह्मी स्थितिः पार्थ नैनां प्राप्य विमुह्यति। स्थित्वास्यामन्तकालेपि ब्रह्म निर्वाणमृच्छति ॥७२॥
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.
ब्राह्मी ब्रह्मविषया। ज्ञानिनामप्यन्तकाले अन्यमनसां प्रारब्धकर्मभावात् जन्मान्तरम्। प्रारब्ध कर्मनाशकाले नियमेन भगवत्स्मृऽतिर्भवति। ततो मोक्षश्च।
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.
"यं यं वापि स्मरन् भावम्"
"Whatever mental thought the departing person remembers..."
इति हि वक्ष्यति।
is stated thus in Bhagavad Gita itself, in 8.6 verse.
बाणं शरीरम्।
The word 'bāṇaṁ' means physical body.
"अभावात् जडदेहस्य विष्णुर्निर्वाण उच्यते। भिन्नदेहाभावतो वा स सहस्रशिरा अपि॥"
"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."
इति च ॥७२॥
-states testimonial.
॥इति श्रीमदानन्दतीर्थभगवत्पादाचार्यविरचिते श्रीभगवद्गीतातात्पर्यनिर्णये द्वितीयोध्यायः॥
Thus, purport composed by his holiness Srimad Anandatheertha on Bhagavad Gita, second chapter is complete.
॥ओं तत्सदिति श्रीमद्भगवद्गीतासु उपनिषत्सु ब्रह्मविद्यायां योगशास्त्रे श्रीकृष्णार्जुनसंवादे साङ्ख्ययोगो नाम द्वितीयोध्यायः॥
Thus ends the second chapter, titled Sāṅkhyayōga, from the conversation between Krishna and Arjuna, called Bhagavad Gita, which is an Upanishad that provides wisdom of the Brahman and the method of practicing Yōga.
