Vaishampayana said, "When the diverse detachments of the Pandava and the Kuru armies were drawn up in battle array and when Arjuna became dispirited, the holy one himself explained the question of what is the end and what is not the end attained by persons of different characters. I have before this recited to you the words of the holy one. It is difficult to understand the religion preached by the holy one on that occasion. Men of impure souls cannot apprehend it at all.
वैशम्पायन उवाच समुपोढेष्वनीकेषु कुरुपाण्डवयोर्मधे। अर्जुने विमनस्के च गीता भगवता स्वयम्॥ अगतिश्च गतिश्चैव पूर्वं ते कथिता मया। गहनो ह्येष धर्मो वै दुर्विज्ञेयोऽकृतात्मभिः॥
