Balarama was surprised. This extraordinary show of affection, He thought, was something mystical, performed either by the demigods or some wonderful man. Otherwise, how could this wonderful change take place? This maya might be some raksasi-maya, He thought, but how can raksasi-maya have any influence upon Me? This is not possible. Therefore it must be the maya of Krsna. He thus concluded that the mystical change must have been caused by Krsna, whom Balarama considered His worshipable personality of Godhead. He thought, It was arranged by Krsna, and even I could not check its mystic power. Thus Balarama understood that all these boys and calves were only expansions of Krsna.
