"When a Brahmana loses his means of livelihood and is visited by distress, he may certainly act like a Vaishya and derive his support by agriculture and tending cattle, if, of course, he is not capable to perform Kshatriya duties.'
भीष्म उवाच अशक्तः क्षत्रधर्मेण वैश्यधर्मेण वर्तयेत्। कृषिगोरक्ष्यमास्थाय व्यसने वृत्तिसंक्षये॥
