Purport: 

Śrīla Viśvanātha Cakravartī Ṭhākura explains that the severe distress Indra apparently inflicted upon the residents of Vṛndāvana was an arrangement made by Śrī Kṛṣṇa’s pastime potency to enhance the loving dealings between the residents and the Lord. The ācārya gives the analogy that for a hungry person, the pain of hunger increases the happiness he feels when he finally eats excellent food, and thus hunger can be said to enhance the pleasure of eating. Similarly, the residents of Vṛndāvana, although not experiencing ordinary, material anxiety, felt a type of distress at the activities of Indra and thus intensified their meditation on Kṛṣṇa. When the Lord finally acted, the result was wonderful.
