B.G 2.54

अर्जुन उवाच। स्थितप्रज्ञस्य का भाषा समाधिस्थस्य केशव। स्थितधीः किं प्रभाषेत किमासीत व्रजेत किम् ॥२-५४॥

arjuna uvāca। sthitaprajñasya kā bhāṣā samādhisthasya kēśava। sthitadhīḥ kiṁ prabhāṣēta kimāsīta vrajēta kim ॥2-54॥

Arjuna said: O Keshava, What are the characteristics of the one who is stationed in practical wisdom when he is in an equanimous state (samādhi)? Stationed in his intellect, how does he speak? With what attitude does he sit? How does he walk?

Gīta Bhāshya 2.54

'sthitaprajna' - one who is established in practical wisdom; 'bhāshā' - ascertained characteristics; 'samādhistha' - one who is stationed in Samādhi; 'Kēshava' - one who administers the creation and destruction activities of the universe; 'kimāsīt' - 'With what attitude does he sit?'; In Puranas, great Kings, and sages enquire about dharma, so that people can grasp the knowledge. It doesn't mean Arjuna is ignorant.

'sthitaprajna' - is one who is established in the wisdom, i.e. practical knowledge. The term 'bhāshā' means 'as it shines', means ascertained characteristics. The characteristics that differ from normal is being enquired, hence the explicit term 'samādhistha' , i.e. one who is stationed in Samādhi.

'kam' means creator, Brahma; 'Īsa' means destroyer, Rudra; and 'va' means one who controls; Thus, the lord is addressed as - 'Kēshava'. In Harivamsha, in the episode concerning travel to the Himalaya mountain, a similar meaning is given by lord Rudra to the word 'Kēshava'.

"One with golden womb, i.e. Brahma, is conveyed by 'Ka', and 'Īsa' means Shankara. Creation and such activities are administered by you, hence O lord, you are called 'Kēshava'."

- is the proverb, as well.

'kimāsīt' - 'With what attitude does he sit?'

It doesn't mean Arjuna is not aware of those characteristics:

"Certainly, the ancient kings and sages have an understanding. Even then, they ask regarding 'dharma' in the Purānas to spread the secret treasure. Those with little intelligence do not recognize it as secret knowledge."

- thus state proverb.

Gīta Tātparya 2.54

'kā bhāṣā' - by what qualities he is recognized. 'samādhisthasya' - who is devoid of defective intelligence.

'kā bhāṣā' means 'how is he recognised?', i.e. 'by what qualities?'. 'samādhisthasya' means one who is devoid of defective intelligence.
