B.G 3.42 and 43
इंद्रियाणि पराण्याहुरिंद्रियेभ्यः परं मनः। मनसस्तु परा बुद्धिर्यो बुद्धेः परतस्तु सः ॥४२॥
It is declared, the mind is higher than senses among the faculties, higher than mind is the intellect. That which is higher than intellect is, but He (the lord).
एवं बुद्धेः परं बुद्ध्वा संस्तभ्यात्मानमात्मना। जहि शत्रुं महाबाहो कामरूपं दुरासदम् ॥४३॥
O mighty armed, in this way, having realized that which is higher than intellect, having restrained the mind with the help of intellect, conquer the enemy in the form of desire, which is difficult to restrain.
Gīta Bhāshya 3.42 and 43
In order to kill the enemy, desire, one must use the weapon in the form of intellect. Object to be known is the Supreme Being, who is beyond the unmanifest Prakrti. 'ātmānam' = the mind. 'ātmanā' = with the help of intellect. In the current context word 'ātman' does not refer to individual being.
शत्रुहनन आयुधरूपं ज्ञानं वक्तुं ज्ञेयम् आह - इंद्रियाणीति॥
In order to kill the enemy, the weapon in the form of knowledge is conveyed, and also the object to be known is stated in the verse 'indriyanam'.
"असङ्गज्ञानासिमादाय तरातिपारम्"
इति ह्युक्तम्।
"From the detachment obtained through the limits of knowledge, crosses over to the other shore."
- thus states the testimonial.
शरीरात् इन्द्रियाणि पराणि उत्कृष्टानि। न केवलं बुद्धेः परः। श्रुत्युक्तप्रकारेण अव्यक्तादपि।
Compared to the body, the faculties are beyond (para), which means superior. He, the lord is not just superior to the intellect, He is superior even to the unmanifest Prakrti as declared in the Vēdas.
"अव्यक्तात् पुरुषः परः"
इति श्रुतिः।
"The Supreme being is superior compared to the unmanifest Prakrti."
-thus states the Vēdas.
न च तत्र तत्रोक्त ऐकदेशज्ञानमात्रेण भवति मुक्तिः। सार्वत्रिकगुणोपसंहारो हि भगवता गुणोपसंहार पादे अभिहितः-
One does not obtain liberation (mukti) just by this single instruction given in one context. Indeed, (liberation is obtained) by having all the auspicious qualities at once, at the same time, as explained in Brahma Sūtra, 'guṇōpasaṁhāra' section:
"आनन्दादयः प्रधानस्य" (३.३.१२)
इत्यादिना।
"The blissful nature, etc. is the primary."
-such other statements.
तथा चान्यत्र-
Same is stated in other places as well:
"अपौरुषेयवेदेषु विष्णुवेदेषु चैव हि। सर्वत्र ये गुणाः प्रोक्ताः सम्प्रदायागताश्च ये। सर्वैस्तैः सह विज्ञाय ये पश्यन्ति परं हरिम्। तेषामेव भवेन्मुक्तिः नान्यथा तु कथञ्चन॥"
इति गारुडे।
"Among the Vēdas that are of non-human origin, and among all the Vishnu scriptures received through tradition, everywhere qualities are stated. By studying all of them, we understand the lord Hari who is beyond. Indeed, by them alone one gets liberation, not otherwise in any other way."
- thus states Garuda Purāna
तस्मात् अव्यक्तादपि परत्वेन ज्ञेयः। न चात्र जीवः उच्यते।
Therefore, the object to be known is even beyond the unmanifest Prakrti. The individual being is not referred here ( by the word 'Ātman').
"रसोऽप्यस्य परं दृष्ट्वा"
इत्युक्तत्वात्।
"Even that hunger for taste disappears by seeing that Devine lord."
-it is already stated thus (in 2.59).
"अविज्ञाय परं मत्तो जयः कामस्य वै कुतः"
इति च।
"Indeed, without knowing my divine form that is beyond, how is it possible to conquer the desire by the intoxicated?"
- are also the testimonials.
अतः परमात्मज्ञानमेवात्र विवक्षितम्। आत्मानं मनः। आत्मना बुद्ध्या ॥४२, ४३॥
Hence, the knowledge of the supreme being alone is sought in this context. The word 'ātmānaṁ' means mind. The word 'ātmanā' means
॥इति श्रीमद्भगवद्गीताभाष्ये तृतीयोऽध्यायः॥
Thus ends the Bhagavad Gīta Bhashya, third chapter.
॥ ओं तत्सदिति श्रीमद्भगवद्गीतासु उपनिषत्सु ब्रह्मविद्यायां योगशास्त्रे श्रीकृष्णार्जुनसंवादे कर्मयोगो नाम तृतीयोध्यायः ॥
Ōm, this is indeed truth. In the glorious Bhagavad Gita in the form of a conversation between Krishna and Arjuna, the ancient text that contains spiritual knowledge, that educates regarding the Brahman, the ultimate reality, the science of Yoga, the 3rd chapter named "Yōga of Action", ends.
