श्रीमद् भगवद्गीता

English Translation of Abhinavgupta's Sanskrit Commentary By Dr. S. Sankaranarayan

9.1 Idam etc. Not to entertain displeasure is an important reisite for communicating knowledge. The words Jnana and Vijnana [mean respectively 'knowledge' and 'action'] as above.

English Translation Of Sri Shankaracharya's Sanskrit Commentary By Swami Gambirananda

9.1 Te, to you; anasuyave, who are not given to cavilling, who are free from carping; pravaksyami, I shall speak of; idam, this. The Lord uttered the word 'this' by bearing in mind as an immediately present fact the knowledge of Brahman that will be and was spoken of in the earlier chapters. The word tu (however) is used for pointing out a distinction [The distinction of Knowledge from meditation that was being discussed.]. (I shall speak) of this itself-what is that?-(it is) guhyatamam, the highest secret; and is jnanam, Knowledge, complete Knowledge-nothing else-, the direct means to Liberation, as stated in the Upanisads and the Smrtis, 'Vasudeva is all' (7.19), 'the Self verily is all this' (Ch. 7.25.2), 'One only, without a second' (op. cit. 6.2.1), etc., and also as stated in such Upanisadic texts as, 'On the other hand, those who understand otherwise than this come under a different ruler, and belong to the worlds that are subject to decay' (op. cit. 7.25.2). (Knowledge) of what kind? It is vijnana-sahitam, combined with experience; jnatva, by realizing, by attaining; yat, which Knowledge; moksyase, you shall be free; asubhat, from evil, from worldly bondage.

English Translation of Ramanuja's Sanskrit Commentary By Swami Adidevananda

9.1 The Lord said I will declare to you, who does not cavil, this most mysterious knowledge called Upasana, which is of the nature of Bhakti, together with special knowledge, namely, the distinguishing knowledge of how it differs from other meditations. The import is this: You have heard of My eminence, which is distinct in kind from all other forms of greatness and is unlimited in its modes. You must have been convinced that it can be so only and not otherwise. To you whose mind is thus prepared, I shall declare that knowledge by aciring which, and making which your way of life, you will be emancipated from all evil that hinders you from attaining Me.
