Bhagavad Gita 2.54अर्जुन उवाच स्थितप्रज्ञस्य का भाषा समाधिस्थस्य केशव।स्थितधीः किं प्रभाषेत किमासीत व्रजेत किम् ॥

Arjuna wants to know from Lord Krishna the characteristic marks of one who is established in the Self in Samadhi how he speaks, how he sits, how he moves about.The characteristic marks of the sage of steady wisdom and the means of attaining that steady knowledge of the Self are described in the verses from 55 to 72 of this chapter.Steady wisdom is settled knowledge of ones identity with Brahman attained by direct realisation. (Cf.XIV.21, 27).
