"चित्ते प्रसन्ने भुवनं प्रसन्नं चित्ते विषण्णे भुवनं विषण्णम् ।
अतोऽभिलाषो यदि ते सुखे स्यात् चित्तप्रसादे प्रथमं यतस्व॥" Elucidation: If the mind is happy, the entire world seems happy. If the mind is despondent, the entire world seems despondent. Hence, if you desire happiness, strive towards the happiness of the mind first.
