While watching the rāsa dance performed by Lord Kṛṣṇa and the gopīs, Lord Śiva beheld the beautiful face of Kṛṣṇa and immediately began to dance and beat upon his small ḍiṇḍima drum. While Lord Śiva was dancing in ecstasy, his eldest son, Ganeśa, joined him. Rolling on the Ground
In the Third Canto, 1st Chapter, 31st verse, of Śrīmad-Bhāgavatam, Vidura inquires from Uddhava, "My dear friend, is Akrūra in an auspicious condition? He is not only a learned scholar and sinless, but he is also a devotee of Lord Kṛṣṇa. He has such ecstatic love for Kṛṣṇa that I have seen him rolling upon Kṛṣṇa's footprints in the dust as if bereft of all senses." Similarly, one gopī gave a message to Kṛṣṇa that Rādhārāṇī, because of Her separation from Him and because of Her enchantment with the flavor of His flower garlands, was rolling on the ground, thereby bruising Her soft body.
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.
