There is a statement by Yāmunācārya to this effect: "Since I have begun to enjoy these transcendental exchanges of love, which are always newer and newer, whenever I remember the pleasure of past sex life, my lips curl and I wish to spit on the idea." This is an instance of ecstatic love in ghastliness.
Dread
One old devotee said, "My dear Lord, when we are away from You we become so anxious to see You again, and there is great misery in our lives. But then, when we do see You, there immediately comes the fear of separation. Under the circumstances, both when we see You and when we do not see You, we are subjected to different kinds of tribulation." This is an instance of a contradictory mixture of ecstatic love for Kṛṣṇa. Such ecstatic love is palatable, and expert critics have compared such ecstatic love with a mixture of curd, sugar candy and a little black pepper. The combined taste is very palatable.
