Bhagavad Gita · Karma Sannyasa YogaChapter 5, Shloka 10 (5.10)

The lotus leaf. It lives in water and seems wet with water — but the water does not stay on it; it simply rolls off. In the same way, the karma yogi, living in the midst of action, remains untainted by bondage.

Shankaracharya — the spirit of a servant. Brahmaṇi īśvare ādhāya nikṣipya "tad-arthaṃ karma karomi" iti bhṛtya iva svāmy-arthaṃ — offering to Ishvara, "I act for His sake" — like a servant for the master; mokṣe 'pi phale saṅgaṃ tyaktvā — giving up attachment even to the fruit of moksha. The fruit: kevalaṃ sattva-śuddhi-mātram eva phalaṃ tasya karmaṇaḥ syāt — the only fruit of that action is the purification of the inner being.

Acharya Ramanuja — placing actions in prakriti. Indriyāṇāṃ prakṛti-pariṇāma-viśeṣa-rūpatvena indriyākāreṇa avasthitāyāṃ prakṛtau — the senses are themselves a product of prakriti; placing action in prakriti, which exists in the form of those senses, in the manner of 5.8–5.9 ("the senses are doing it"), giving up attachment to the fruit, and acting with the thought "I do nothing at all", one prakṛty-ātmābhimāna-rūpeṇa sambandha-hetunā pāpena na lipyate — is not tainted by the sin that causes bondage, namely taking prakriti to be the self.
