महाभारत - शान्तिपर्व - तृष्ण

यच्च कामसुखं लोके यच्च दिव्यं महत्सुखम् |
तृष्णाक्षयसुखस्यैते नार्हतः षोडशीयं कलाम् ||

- महाभारत, शान्तिपर्व

The happiness got by satisfying your desires, or the happiness got in heaven does not even match up to a sixteenth portion of the real happiness that is attained through limiting your desires.

- Mahabharata, Shantiparva
