What do we get as a reward for studying one of the longest chapters of the Gita? It is this concluding shloka of the eleventh chapter which Shankaraachaarya considers the essence of the entire Bhagavad Gita. Shri Krishna says that Isvara can be attained by following five guidelines : perform actions for the sake of Ishvara, fix Ishvara as the ultimate goal, observe single-pointed devotion to Ishvara, remain free from worldly attachments, do not harbour likes or dislikes.
We have come across these themes throughout the Gita, but this is the first time that Shri Krishna reveals how they come together as a logical whole. First, he advises us to follow karma yoga, to perform selfless actions by dedicating them to Ishvara. He then advises us to fix Ishvara as the ultimate goal. This is the yoga of knowledge or jnyaana yoga. But we need something that propels us from karma yoga to jnyaana yoga. That is revealed as the third step, the yoga of devotion or bhakti yoga. None of these steps can be accomplished with a mind filled with the impurities of likes and dislikes that generate material attachment. These are addressed in fourth and fifth steps which are freedom from worldly attachments as well as from likes and dislikes.
Furthermore, all five steps are interconnected and strengthen each other. The mind cannot fully detach itself from everything. Like a child that drops attachment to toys and is attached to higher ideals as an adult, Shri Krishna advises us to drop attachments to material things and develop attachment for Ishvara. When we begin to see everything as Ishvara, and see ourselves as part of Ishvara, we will not generate feelings of dislike towards anyone or anything, just like we do not have enmity towards any part of our own body. This is the theme of this chapter, where the individual essence sees itself as part of the universal eternal essence.
