Bhagavad Gita Chapter 5.10
brahmaṇy ādhāya karmāṇi
sańgaḿ tyaktvā karoti yaḥ
lipyate na sa pāpena
padma-patram ivāmbhasā
Translation
One who performs his duty without attachment, surrendering the results unto the Supreme Lord, is unaffected by sinful action, as the lotus leaf is untouched by water.
