महाभारत - अरण्य - वित्त वैरग्य

धर्मार्थं यस्य वित्तेहा वरं तस्य निरेहता ।
प्रक्षालनाद्धि पंकस्य श्रेयो न स्पर्शनं नृणाम् ॥

- महाभारत, अरण्य

dharmArthaM yasya vittehA varaM tasya nirehatA ।
prakShAlanAddhi pankasya shreyo na sparshanam nRuNAm ॥

- mahAbhArata, araNya

If one wants wealth only so that he can spend it on Dharma (charity and other noble deeds), then it is better to give up the longing. It is better keep your feet clean by staying away from mud than clean it after getting dirty.

- Mahabharata, Aranya
