स एवायं मया तेऽद्य योगः प्रोक्तः पुरातनः।
भक्तोऽसि मे सखा चेति रहस्यं ह्येतदुत्तमम्।।4.3।।
।।4.3।।तू मेरा भक्त और प्रिय सखा है इसलिये वही यह पुरातन योग आज मैंने तुझसे कहा है क्योंकि यह बड़ा उत्तम रहस्य है।
4.3 Sah, that; puratanah, ancient; yogah, Yoga; eva, itself; ayam, which is this; proktah, has been taught; te, to you; maya, by Me; adya, today; iti, considering that; asi, you are; me, My; bhaktah, devotee; ca sakha, and friend. Hi, for; etat, this Yoga, i.e. Knowledge; is a uttamam, profound; rahasyam, secret. Lest someone should understand that the Lord has said something contradictory, therefore, in order to prevent that (doubt), as though raising a estion,
4.1-3 Evam etc. upto uttamam. Eventhough it has come down by regular succession of teacher, it is lost now. By this [statement] the Bhagavat indicates the rarity (or difficulty) and respectability of this knowledge. You are My devotee and friend too : You are a devotee having nothing but Me as your final goal and you are a friend too. This too indicates the secondary importance [of the friendship]. Hence, just as in the sentence wander begging food [etc], the importance lies in the act of begging food, but unimportance in the act of bringing the cow; in the same way, in the present case it is devotion towards the teacher that is important and not the friendship also. This is the idea intended here.
4.3 It is the same ancient, unchanged Yoga which is now taught to you, who out of friendship and overwhelming devotion have resorted to Me whole-heartedly. The meaning is that it has been taught to you fully with all its accessories. Because it is the most mysterious knowledge declared in the Vedanta, it cannot be known or taught by anyone other than Myself. In this connection, in order to know the truth about the Lords descent correctly, Arjuna asked:
Sa evaayam mayaa te’dya yogah proktah puraatanah; Bhakto’si me sakhaa cheti rahasyam hyetad uttamam.
saḥ—that; eva—certainly; ayam—this; mayā—by me; te—unto you; adya—today; yogaḥ—the science of Yog; proktaḥ—reveal; purātanaḥ—ancient; bhaktaḥ—devotee; asi—you are; me—my; sakhā—friend; cha—and; iti—therefore; rahasyam—secret; hi—certainly; etat—this; uttamam—supreme
