There is a statement in Govinda-vilāsa to this effect: "Śrīmatī Rādhārāṇī was looking for Kṛṣṇa very anxiously and almost disappointedly." When there is such indirect expression of conjugal love, there is smiling, astonishment, enthusiasm, lamentation, anger, dread and sometimes ghastliness. These seven exchanges of conjugal love form another state of ecstatic love.
In a direct relationship of conjugal love, there is laughter, astonishment, chivalry, lamentation, anger and dread, but there is no ghastliness. These expressions are considered to be the great reservoirs of pleasure. When these seven kinds of ecstatic loving exchanges are manifested, they attain the status of steadiness by which the taste of conjugal love expands.
Laughter
After He had stolen some curd from the pots of two gopīs, Kṛṣṇa told one of His gopī friends: "My dear beautiful friend, I can take oath that I have not stolen even a drop of curd from your pot! But still, your friend, Rādhārāṇī, is very shamelessly smelling the flavor of My mouth. Kindly forbid Her from this devious policy of putting Her face near Mine." When Kṛṣṇa was speaking like this, the friends of Rādhārāṇī could not check their laughter. This is an instance of ecstasy in conjugal love.
Astonishment
Once Brahmā was watching all the cows and the cowherd boys dressed in yellow garments and decorated with valuable jewels. The boys were expanding their four arms and were being worshiped by many hundreds of other Brahmās. All the cowherd boys began to express their joyfulness for being with Kṛṣṇa, the supreme Brahman. At that time, Brahmā showed his astonishment by exclaiming, "What am I seeing here?" This is an instance of astonishment in ecstatic love.
