Mahabharata Aswamedha Parva Chapter 51:3

Mahabharata Aswamedha Parva (Anugita Parva) Chapter 51:3 Expelling all impressions and restraining the Soul in the Soul, he understands that auspicious Brahman than which nothing greater exists. Upon the understanding becoming clear, he succeeds in attaining to tranquillity. The indication of tranquillity is like what takes place in a dream. This is the goal of those emancipated ones who are intent on knowledge. They behold all those movements which are born of successive developments. This is the goal of those who are unattached to the world. This is the eternal usage. This is the acquisition of men of knowledge. This is the uncensured mode of conduct. This goal is capable of being attained by one that is alike to all creatures, that is without attachment, that is without expectations, and that looks equally on all things. I have now declared everything to you, ye foremost of regenerate Rishis. Do you act in this way forthwith; you will then acquire success." The preceptor continued, 'Thus addressed by the preceptor Brahma, those high-souled sages acted accordingly and then attained to many regions (of great felicity). Do thou also, O blessed one, duly act according to the words of Brahma as declared by me, O thou of pure soul. Thou wilt then attain to success. Vasudeva said,—"Thus instructed in the principles of high religion by the preceptor, the pupil, O son of Kunti, did everything accordingly, and then attained to Emancipation. Having done all that he should have done, the pupil, O perpetuator of Kuru's race, attained to that seat repairing whither one has not to grieve." Arjuna said, "Who, indeed, was that Brahmana, O Krishna, and who the pupil, O Janarddana. Truly, if it is fit to be heard by me, do thou then tell me, O lord!" Vasudeva said, "I am the preceptor, O mighty-armed one, and know that the mind is my pupil. Through my affection for thee, O Dhananjaya, I have related this mystery to thee. If thou hast any love for me, O perpetuator of Kuru's race, do thou then, after having heard these instructions relating to the Soul, always act duly (according to them), O thou of excellent vows. Then when this religion has been duly practised, O mower of foes, thou wilt become freed from all thy sins and attain to absolute emancipation. Formerly, when the hour of battle came, this very religion, O thou of mighty arms, was declared by me (to thee)! Do thou, therefore, set thy mind on it. And now, O chief of Bharata's race, it is long since that I saw the lord my sire. I wish to see him again, with thy leave, O Phalguna!"' Vaisampayana continued, 'Unto Krishna who had said so, Dhananjaya said in reply,—"We shall go to-day from this town to the city called after the elephant. Meeting king Yudhishthira of virtuous soul there, and informing him (of thy intention) thou shalt then repair to thy own city!
