One gopī informed Kṛṣṇa that when Śrīmatī Rādhārāṇī was singing about His glories, She enchanted all of Her friends in such a way that they became stonelike and dull. At the same time, the nearby stones began to melt away in ecstatic love.
Stretching the Body
When there was stretching of the body of Nārada Muni from chanting the Hare Kṛṣṇa mantra, he chanted so loudly that it was apprehended that Lord Nṛsiṁha had appeared. Thus all the demons began to flee in different directions. It is also said that sometimes when Nārada, the carrier of the vīṇā, remembers his Lord Kṛṣṇa in great ecstasy, he begins to stretch his body so vigorously that his sacred thread gives way.
Crying Loudly
A gopī once said to Kṛṣṇa: "My dear son of Nanda Mahārāj, by the sound of Your flute Śrīmatī Rādhārāṇī has become full of lamentation and fear, and thus, with faltering voice, She is crying like a kurobi bird.
It is described that by hearing the vibration of Kṛṣṇa's flute Lord Śiva becomes very puzzled and begins to cry so loudly into space that the demons become vanquished and the devotees become overwhelmed with joy.
