Vemacitrin is the most prominent of the leaders of the Asuras in their fight with the devas of Trāyastriṃśa where they had formerly lived. After one battle he was made prisoner and bound before the throne of Śakra, ruler of Trāyastriṃśa, whom he treated with bitter verbal abuse. Śakra bore his insults patiently, and argued that such patience was a sign of strength, not of weakness. (Vepacitti-sutta, SN.xi.4) Vemacitrin's daughter was named Sujā (or Sujātā). After a courtship that extended over many lives, Sujā married Śakra and Vemacitrin became his enemy's father-in-law.
