dṛṣṭvā tam āgataḿ pārthā
mukundam akhileśvaram
uttasthur yugapad vīrāḥ
prāṇā mukhyam ivāgatam
drishtva -- seeing; tam -- Him; agatam -- arrived; parthah -- the sons of Pritha (Kunti); mukundam -- Krishna; akhila -- of everything; isvaram -- the Lord; uttasthuh -- they stood up; yugapat -- all at once; virah -- heroes; pranah -- the senses; mukhyam -- their chief, the vital air; iva -- as; agatam -- returned.
When the Pandavas saw that Lord Mukunda had arrived, those heroic sons of Pritha all stood up at once, like the senses responding to the return of the life air.
The metaphor used here is quite poetic. When a person is unconscious, the senses do not function. But when consciousness returns to the body, all the senses spring to life at once and begin functioning. Similarly, the Pandavas all stood up at once, enlivened to receive their Lord, Sri Krishna.
