PURPORT

Krsna's heaviness was unbearable for the child's mother, but when Trnavartasura came, he immediately carried the child away. This was another demonstration of Krsna's inconceivable energy. When the Trnavarta demon came, Krsna became lighter than the grass so that the demon could carry Him away. This was ananda-cinmaya-rasa, Krsna's blissful, transcendental pleasure.
