When one is forced to act in a way which is forbidden, or to refrain from acting in a way which is proper, he becomes regretful and thinks himself dishonored. At that time there is a sense of disappointment. In this kind of disappointment one becomes full of anxiety, sheds tears, changes bodily color, feels humility and breathes heavily.
When Kṛṣṇa, in punishing the Kāliya serpent, appeared to have drowned Himself in the poisonous water of the Yamunā, Nanda Mahārāja addressed Yaśodā-devī thus: "My dear wife, Kṛṣṇa has gone deep into the water, and so there is no longer any need to maintain our bodies, which are so full of sinful activities! Let us also enter into the poisonous water of the Yamunā and compensate for the sinful activities of our lives!" This is an instance of severe shock, wherein the devotee becomes greatly disappointed.
