Although all people within the material world are burning in the great forest fire of lust and greed, you remain free and are not burned by that fire. You are just like an elephant who takes shelter from a forest fire by standing within the water of the Ganges River.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
जनेषु दह्यमानेषु कामलोभदवाग्निना । न तप्यसेऽग्निना मुक्तो गङ्गाम्भःस्थ इव द्विपः
janeṣu dahyamāneṣu kāmalobhadavāgninā | na tapyase'gninā mukto gaṅgāmbhaḥstha iva dvipaḥ
