Bhagavad Gita 5.23

He who, before leaving his body, learns to overcome the promptings of desire and anger, is a saint and is happy.

शक्नोतीहैव यः सोढुं प्राक्शरीरविमोक्षणात्।
कामक्रोधोद्भवं वेगं स युक्तः स सुखी नरः॥

śaknotīhaiva yaḥ soḍhuṃ prākśarīravimokṣaṇāt|
kāmakrodhodbhavaṃ vegaṃ sa yuktaḥ sa sukhī naraḥ||
