In Śrīmad-Bhāgavatam, Tenth Canto, Eighty-sixth Chapter, verse 38, there is a statement of how Śrutadeva, a brāhmaṇa from the country called Mithilā in northern India, became so overpowered with joy as soon as he saw Kṛṣṇa that immediately after bowing to the Lord's lotus feet he stood up and began to dance, raising his two arms above his head.
One of the devotees of Lord Kṛṣṇa once addressed Him in this manner: "My dear Lord, although You are not a professional dancer, by Your dancing You have so astonished us that we can understand that You are personally the master of all dancing. Certainly You must have learned this dancing art directly from the goddess of love." When a devotee dances in ecstatic love, there are manifestations of symptoms which are called sāttvika. Sāttvika means that they are from the transcendental platform. They are not symptoms of material emotion; they come from the soul proper.
In Śrīmad-Bhāgavatam, Tenth Canto, Eighty-fifth Chapter, verse 38, Śukadeva Gosvāmī tells Mahārāja Parīkṣit that after surrendering everything unto the lotus feet of Vāmanadeva, Bali Mahārāja immediately caught hold of the lotus feet of the Lord and pressed them to his heart. Being overwhelmed with joy, he manifested all the symptoms of ecstatic love, with tears in his eyes and a faltering voice.
In such expressions of ecstatic love there are many other subsidiary symptoms, such as jubilation, withering, silence, disappointment, moroseness, reverence, thoughtfulness, remembrance, doubtfulness, confidence, eagerness, indifference, restlessness, impudence, shyness, inertness, illusion, madness, ghastliness, contemplation, dreaming, disease and signs of death. When a devotee meets Kṛṣṇa, there are symptoms of jubilation, pride and perseverance, and when he is feeling great separation from Kṛṣṇa, the symptoms of ghastliness, disease and signs of death become prominent.
It is stated in the First Canto of Śrīmad-Bhāgavatam, Eleventh Chapter, verse 5, that when Lord Kṛṣṇa returned from the Battlefield of Kurukṣetra to His home at Dvārakā, all the residents of Dvārakā began to talk with Him, as a child talks lovingly to his father after the father's return from foreign countries. This is an example of jubilation.
When Bahulāśva, the King of Mithilā, saw Kṛṣṇa at his palace, he decided to offer his respects by bowing down before Him at least a hundred times, but he was so overcome by feelings of love that after bowing down only once, he forgot his position and could not rise again.
In the Skanda Purāṇa a devotee tells Lord Kṛṣṇa, "My dear Lord, as the sun evaporates all the water on the ground by its scorching heat, so my mental state has dried away the luster of my face and body, due to separation from You." This is an example of withering in ecstatic love.
An expression of disappointment was made by Indra, the King of heaven. When he saw the sun-god, Indra told him, "My dear sun-god, your sunshine is very glorious because it reaches unto the lotus feet of Lord Kṛṣṇa, the master of the Yadu dynasty. I have thousands of eyes, but they have proved to be useless because not even for a moment are they able to see the lotus feet of the Lord."
