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

śhaknotīhaiva yaḥ soḍhuṁ prāk śharīra-vimokṣhaṇāt kāma-krodhodbhavaṁ vegaṁ sa yuktaḥ sa sukhī naraḥ

One who is able to withstand the impulse arising from desire and anger, even before giving up the body — that person is a yogi, that person is truly happy.
