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.
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.
It is said that when the full moon rises, the lotus petals become expanded. Similarly, when Kṛṣṇa used to appear before Rādhārāṇī, Her face, which is compared with the lotus flower, would expand by Her yawning.
As far as breathing heavily is concerned, it is stated: "Lalitā (one of the gopīs) is just like a cātakī bird, which only takes water falling directly from the rain cloud and not from any other source." In this statement Kṛṣṇa is compared to the dark cloud, and Lalitā is compared to the cātakī bird seeking only Kṛṣṇa's company. The metaphor continues to say, "As a heavy wind sometimes disperses a mighty cloud, so the heavy breath from Lalitā's nostrils caused her to miss Kṛṣṇa, who had disappeared by the time she recovered herself."
