योगवासिष्ठः yogavāsiṣṭhaḥ - book-6, chapter-53, verse-15

मूर्खस्यापि स्वकर्मैव श्रेयसे किमु सन्मतेः ।
मतिर्गलदहंकारा पतितापि न लिप्यते ॥ १५ ॥

15. mūrkhasya api svakarman eva śreyase kimu sanmateḥ

15. mūrkhasya api svakarman eva
śreyase (bhavati); sanmateḥ kimu

matiḥ patitā api na lipyate

15. One's own action (karma) / duty (dharma) leads to well-being even for a fool; how much more so then for a wise person? An intellect from which ego (ahaṅkāra) has dropped away is not tainted, even if it appears fallen (or engaged in actions typically considered impure).
