Srimad Bhagavatam Canto 09, Chapter 09, Text 33

SB 9.9.33

evam karuna-bhasinya
 vilapantya anathavat
vyaghrah pasum ivakhadat
 saudasah sapa-mohitah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Being condemned by the curse of Vasistha, King Saudasa devoured the brahmana, exactly as a tiger eats its prey. Even though the brahmana’s wife spoke so pitiably, Saudasa was unmoved by her lamentation.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
This is an example of destiny. King Saudasa was condemned by the curse of Vasistha, and therefore even though he was well qualified he could not restrain himself from becoming a tigerlike Raksasa, for this was his destiny. Tal labhyate duhkhavad anyatah sukham (Bhag. 1.5.18). As one is put into distress by destiny, destiny can also put one in a happy situation. Destiny is extremely strong, but one can change destiny if one comes to the platform of Krsna consciousness. Karmani nirdahati kintu ca bhakti-bhajam (Brahma-samhita 5.54).
