इति गुह्यतमं शास्त्रमिदमुक्तं मयाऽनघ।
एतद्बुद्ध्वा बुद्धिमान्स्यात्कृतकृत्यश्च भारत।।15.20।।
।।15.20।।हे निष्पाप अर्जुन इस प्रकार यह अत्यन्त गोपनीय शास्त्र मेरे द्वारा कहा गया है। हे भरतवंशी अर्जुन इसको जानकर मनुष्य ज्ञानवान् (तथा प्राप्तप्राप्तव्य) और कृतकृत्य हो जाता है।
15.20 This guhyatamam, most secret, i.e. most mystical;- what is that?-sastram, scripture-. Although the Gita as a whole is spoken of as the scripture, still this chapter itself is here referred to as such, and this for eulogy as is evident from the context. For, not only has the entire meaning of the scripture Gita been stated here in brief, but the whole purport of the Vedas also has been comprehended here. And it has been said, He who realizes it is a knower of the Vedas (1), I alone am the object to be known through all the Vedas (15). (Thus, this most secret scripture) iti uktam, has thus been uttered; maya, by Me; anagha, O sinless one. O scion of the Bharata dynasty, buddhva, under-standing; etat, this, the scripture which has the purport as has been revealed; syat, one becomes; buddhiman, wise; and krta-krtyah, has his duties fulfilled; but not otherwise. The meaning is that what-ever a Brahmana has to do as a conseence of his special birth (as a Brahmana), all that becomes accomplished when the reality of the Lord is known. The idea is that nobodys duties become fulfilled in any other way. And it has been said, O son of Prtha, all actions in their totality culminate in Knowledge (4.33). There is also a saying from Manu: This, verily, is the fulfilment of a Brahmana in particular. For, by getting this, a twice-born has his duties fulfilled; not otherwise (Ma. Sm. 12.93). Since you have heard from Me this truth about the supreme Reality, therefore, O scion of the Bharata dynasty, you have achieved your Goal!
15.20 Iti etc. The most secret [scripture] : Because it explains the oneness of all. One becomes a man of wisdom by knowing this only and not by the knowledge of worldly affairs. One becomes a man of success by just understanding this, and not even by the deeds like the total victory over the foes, earning wealth, enjoying women and so on. The word ca also indicates a wonder. Has it not been witnessed that [always] one becomes a man of success by what has been accomplished ? But it is strange that [in the present case one becomes a man of success] by just what has been realised. The word iti thus indicates the conclusion of the treatise. For, what is to be taught has come to an end completely. That is why in the Sixteenth Chapter the eligibility of the pupil, Arjuna, is exclusively dealt with; and nothing new is taught. The intention [of that chapter] is to say only this much : The divine wealth is just of that nature; but the devilish wealth born of illusion is of this nature; you (Arjuna) are however endowed with the divine wealth of wisdom. Hence [the Lord] is going to say Dont worry. [You are endowed] with the divine wealth (XVI, 5). That is why earlier in the context of explaining the clash between the wisdom and ignorance this has been indicated [by me (Ag.)]: It is the confrontation between the wisdom and ignorance that has been detailed under the pretext of [describing] the wars between the gods and devils. So, while dealing essentially with the ality of a pupil, other subjects are mentioned incidentally. So also the pair of chapters (Ch. XVII & XVIII) would follow. But the teaching [proper] has come to an end completely here itself. For what is to be achieved is nothing but serving (attaining) the Absolute Lord-the serving, which is of the nature of total absorption into Him by ones entire being. All other things are only to achieve this end. This has been explained earlier. The Supreme Happiness is indeed nothing but a complete absorption into the Supreme Lord by ones entire being.
15.20 Thus, this Sastra, the most mysterious of all mysteries and which teaches My aspect as the Supreme Person, has been imparted to you by Me, as you are worthy to receive it because you are sinless. By understanding this, a man will become truly wise and will have fulfilled his duty. Whatever wisdom has to be cultivated for attaining Me, all that should be taken as cultivated and that whatever duty has to be fulfilled in that connection - all that is to be taken as fulfilled by knowing this (the Purusottama Vidya). He gets all spiritual fulfilment by this knowledge, except the direct vision of Purusottama. [Probably the idea is that direct vision comes only when the body falls at the end of the antum of Karma that has brought it into existence. Before that only the state of the Sthitaprajna can be attained. The thin veil of residual Karma still stands in the way.]
