Mahabharata Bhishma Parva Chapter 42:4

Mahabharata Bhishma Parva (Bhagavat-Gita Parva) Chapter 42:4 Bhagavad Gita Chapter XVIII Fixing thy thoughts on Me, thou wilt surmount all difficulties through my grace. But if from self-conceit thou wilt not listen, thou wilt (then) utterly perish. If, having recourse to self-conceit, thou thinkest—I will not fight,—that resolution of thine would be vain, (for) Nature will constrain thee. That which, from delusion, thou dost not wish to do, thou wilt do involuntarily, bound by thy own duty springing from (thy own) nature. The Lord, O Arjuna, dwelleth in the region of the heart of beings, turning all beings as if mounted on a machine, by his illusive power. Seek shelter with Him in every way, O Bharata. Through his grace thou wilt obtain supreme tranquillity, the eternal seat. Thus hath been declared to thee by Me the knowledge that is more mysterious than any (other) matter. Reflecting on it fully, act as thou likest. Once more, listen to my supernal words, the most mysterious of all. Exceedingly dear art thou to Me, therefore, I will declare what is for thy benefit. Set thy heart on Me, become My devotee, sacrifice to Me, bow down to Me. Then shalt thou come to Me. I declare to thee truly, (for) thou art dear to Me. Forsaking all (religious) duties, come to Me as thy sole refuge. I will deliver thee from all sins. Do not grieve. This is not to be ever declared by thee to one who practiseth no austerities, to one who is not a devotee, to one who never waiteth on a preceptor, nor yet to one who calumniateth Me. He who shall inculcate this supreme mystery to those that are devoted to Me, offering Me the highest devotion, will come to Me, freed from (all his) doubts. Amongst men there is none who can do Me a dearer service than he, nor shall any other on earth be dearer to Me than he. And he who will study this holy converse between us, by him will have been offered to Me the sacrifice of knowledge. Such is my opinion. Even the man who, with faith and without cavil, will hear it (read), even he freed (from re-birth), will obtain of the blessed regions of those that perform pious acts. Hath this, O son of Pritha, been heard by thee with mind undirected to any other objects? Hath thy delusion, (caused) by ignorance, been destroyed, O Dhananjaya? Arjuna said, 'My delusion hath been destroyed, and the recollection (of what I am) hath been gained by me, O Undeteriorating one, through thy favour. I am now firm. My doubts have been dispelled. I will do thy bidding.'" Sanjaya continued, "Thus I heard this converse between Vasudeva and the high-souled son of Pritha, (that is) wonderful and causeth the hair to stand on end. Through Vyasa's favour heard I this supreme mystery, this (doctrine of) Yoga, from Krishna himself, the Lord of Yoga, who declared it in person. O King recollecting and (again) recollecting this wonderful (and) holy converse of Kesava and Arjuna, I rejoice over and over again. Recollecting again and again that wonderful form also of Hari, great is my amazement, O king, and I rejoice ever more. Thither where Krishna, the Lord of Yoga (is), thither where the great bowman (Partha) is, thither, in my opinion, are prosperity, and victory, and greatness, and eternal justice [End of the Bhagavad Gita]
