“After conquering all the land on my surface, these proud kings forcibly enter the ocean to conquer the sea itself. What is the use of their self-control, which is aimed at political exploitation? The actual goal of self-control is spiritual liberation.”
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
समुद्रावरणां जित्वा मां विशन्त्यब्धिमोजसा । कियदात्मजयस्यैतन्मुक्तिरात्मजये फलम्
samudrāvaraṇāṃ jitvā māṃ viśantyabdhimojasā | kiyadātmajayasyaitanmuktirātmajaye phalam
