Srimad Bhagavatam Canto 10, Chapter 25, Text 14

 SB 10.25.14

sila-varsati-vatena
 hanyamanam acetanam
niriksya bhagavan mene
 kupitendra-krtam harih
 
Translation: 
 
Seeing the inhabitants of His Gokula rendered practically unconscious by the onslaught of hail and blasting wind, the Supreme Lord Hari understood that this was the work of angry Indra.
 
Purport: 
 
Srila Visvanatha Cakravarti Thakura explains that the severe distress Indra apparently inflicted upon the residents of Vrndavana was an arrangement made by Sri Krsna’s pastime potency to enhance the loving dealings between the residents and the Lord. The acarya 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 Vrndavana, although not experiencing ordinary, material anxiety, felt a type of distress at the activities of Indra and thus intensified their meditation on Krsna. When the Lord finally acted, the result was wonderful.
