Bhagavad Gita · 5.10

ब्रह्मण्याधाय कर्माणि सङ्गं त्यक्त्वा करोति यः।लिप्यते न स पापेन पद्मपत्रमिवाम्भसा॥

brahmaṇy ādhāya karmāṇi saṅgaṁ tyaktvā karoti yaḥ lipyate na sa pāpena padma-patram ivāmbhasā

One who performs all actions surrendering them to Brahman, abandoning attachment, is not tainted by sin — just as a lotus leaf is untouched by water.

— Bhagavad Gita 5.10
