समुद्रावरणां जित्वा मां विशन्त्यब्धिमोजसा ।कियदात्मजयस्यैतन्मुक्तिरात्मजये फलम् ॥ ५ ॥
ITRANS:
samudrāvaraṇāṁ jitvāmāṁ viśanty abdhim ojasākiyad ātma-jayasyaitanmuktir ātma-jaye phalam
Translation:
“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.”
