We had never before, O son of a trader, heard of these subtle doctrines of ascetics who perform only mental Sacrifices. These doctrines are very difficult to understand. It is, therefore, I ask you (about them). The sages of yore were not followers of these doctrines of Yoga. Hence the succeeding sages have not mentioned them.
जाजलिरुवाच न वै मुनीनां शृणुमः स्म तत्त्वं पृच्छामि ते वाणिज कष्टमेतत्। पूर्वे पूर्वे चास्य नावेक्षमाणा नातः परं तमृषयः स्थापयन्ति॥
