Ramayana
धर्माद्राज्यं धनं सौख्यमधर्माद्दुःखमेव च । तस्माद्धर्मं सुखार्थाय कुर्यात्पापं विसर्जयेत् ॥ 7-15-23 ॥
From righteousness come kingdom, wealth, and happiness, but from unrighteousness comes only sorrow; therefore one should practice righteousness for the sake of happiness and cast away sin.
