Sanjaya spoke. Having spoken thus to the son of Pandu, the Blessed One, the son of Vasudeva, again showed His own fourfold-armed form; and, since this one was afraid at the sight of the unfamiliar form, becoming again of the familiar gracious body, He reassured him, the great soul, of true resolve. Of this Lord of all, the supreme Person, the supreme Brahman, the son of Vasudeva who became mortal for the good of the world, the fourfold-armed form is His own; on the entreaty of Vasudeva, afraid of Kamsa, the two arms were withdrawn before the slaying of Kamsa, and made manifest after; for it was entreated, 'God of the gods, born are you, bearing conch, discus, and mace; God, withdraw this divine form by your grace', 'withdraw, self of the universe, this fourfold-armed form'. And for the hater, Shishupala too, the object of ceaseless contemplation was just the fourfold-armed form of the son of Vasudeva, 'with full and noble four arms, bearing conch, discus, and mace'; so here Partha says 'become joined with that very fourfold-armed form'.

His 'own form', as distinct from the universal form, is so called only by the way it appears to the deluded; otherwise that universal form too is His own. The proofs have been given before.
