One should achieve virtue alone singlehanded. Indeed, one should not proclaim himself virtuous and walk with the standard of virtue upraised for purposes of show. They are said to be traders in virtue who practice it for enjoying its fruits.
एक एव चरेद् धर्मे न धर्मध्वजिको भवेत्। धर्मवाणिजका ह्येते ये धर्ममुपभुञ्जते॥
