The sacrifices that one celebrates angrily, the gifts one makes in angrily, the penances one practices angrily, and the offerings and libations one makes to the sacred fire angrily, are such that their merits are robbed by Yama. The toil of an angry man becomes entirely frutile.
यत् क्रोधनो यजति यद् ददाति यद् वा तपस्तप्यति यज्जुहोति। वैवस्वतस्तद्धरतेऽस्य सर्वं मोघः श्रमो भवति हि क्रोधनस्य॥
