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

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

He who acteth, placing all actions in the Eternal, abandoning attachment, is unaffected by sin as a lotus leaf by the waters.

In plain words: Krishna says that a person who does their actions as an offering to the Eternal, without clinging to them, is not stained by wrongdoing. They are like a lotus leaf, which stays dry even in the water.
