There is a symptom of ecstatic love known as concealment, or trying to hide one's real mental condition by externally showing another attitude. In this state of mind one tries to hide his mind by looking away in different directions, by unnecessarily trying for something which is impossible, or by using words which cover one's real thoughts. According to ācāryas expert in the study of psychological activities, these attempts at hiding one's real affections are another part of ecstatic feeling for Kṛṣṇa.
In the Tenth Canto, 32nd Chapter, 14th verse of Śrīmad-Bhāgavatam, Śukadeva Gosvāmī states, "My dear King, the gopīs were always beautiful and decorated with confidential smiles and alluring garments. In their movements, intended to give impetus to lusty feelings, they would sometimes press Kṛṣṇa's hand on their laps, and sometimes they would keep His lotus feet on their breasts. After doing this, they would talk with Kṛṣṇa as if they were very angry with Him."
There is another instance of this concealment in ecstatic love. When Kṛṣṇa, the supreme joker, planted the pārijāta tree in the courtyard of Satyabhāmā, Rukmiṇī, the daughter of King Vīrabhadra, became very angry, but due to her natural gentle behavior, she did not express anything. No one could understand Rukmiṇī's real mental condition. This is an instance of competitive concealment.
There is another instance in the First Canto, 11th Chapter, 28th verse of Śrīmad-Bhāgavatam. After entering Dvārakā, Kṛṣṇa was received in different ways by different members of His family. Upon seeing their husband from a distance, the queens of Dvārakā immediately embraced Him within their minds and slowly glanced over Him. As Kṛṣṇa came nearer, they pushed their sons forward to embrace Him. Others were trying, out of shyness, not to shed tears, but they still could not keep the tears from gliding down. This is an instance of concealment caused by shyness.
