मनुस्मृति - न वैरं कुर्वीत केनचित्

अतिवादांस्तितिक्षेत नावमन्येत कंचन |
न चेमं देहमाश्रित्य वैरं कुर्वीत केनचित् ||

- मनुस्मॄति

One must be patient even when some one provokes you with harsh words. One must never humiliate any one. There is no reason why one must beget enmity with any one for the sake of this impermanent body.

- Manu Smriti
