Shri Krishna had begun a new topic in this chapter, which is the technique by which we can know him as Ishvara in his entirety. Here, Shri Krishna says that he will reveal not just this knowledge, but also impart us wisdom. The wisdom is such that once we know it, there will be nothing else remaining to be known.
 
We spend our lives acquiring knowledge about new things. With the pace of change in the world today, we would not be able to know everything, even if we were to spend thousands of lifetimes gaining PhDs in all the sciences, arts, humanities and so on. Shri Krishna says that the wisdom or “vijnyaana” that he is going to impart will be such that once we know it, nothing else will remain to be known.
 
Let us see how this will be possible. We had seen the example of a goldsmith earlier who is not fascinated by the artwork or shape of the gold bangles, bracelets, necklaces and other ornaments that he comes across. All he cares about is the quantity of gold that is in each ornament. In other words, because he knows the cause as gold, he knows that the effect as the ornament, may differ in shape, but is gold in its essence. Knowledge is the shape of the different ornaments, wisdom is knowledge of their essential nature.
 
What will happen once I know this? Shri Krishna says that having known this, nothing else will remain to be known. It will be knowledge that is all inclusive. Also, it is knowledge that makes up complete, unlike worldly knowledge that reveals further holes as we study it more.
 
But if this is the case, why doesn’t everyone pursue this knowledge? This is taken up next.
