To Thee the troops of Suras enter in, Some with joined palms in awe invoking Thee; Banded Maharshis, Siddhas, cry: "All hail"! Chanting Thy praises with resounding songs.
In plain words: Arjuna sees groups of gods (Suras) entering into Krishna. Some fold their hands in fear and pray. Great sages and perfect beings (Siddhas) shout "Hail!" and sing loud songs of praise.
