Bhagwad Gita
Chapter 2, Verse 70
आपूर्यमाणमचलप्रतिष्ठं
समुद्रमापः प्रविशन्ति यद्वत्।
तद्वत्कामा यं प्रविशन्ति सर्वे
स शान्तिमाप्नोति न कामकामी।।2.70।।
A person who is not disturbed by the incessant flow of desires - that enter like rivers into the ocean which is ever being filled but is always still - can alone achieve peace, and not the man who strives to satisfy such desires.
