Vedanta Philosophy - The Absolute Reality

The purpose of the 16th verse is this. It wants to tell us that we live in this world, we experience everything we are part of this world. We should not forget what we know intellectually very well, that is this world is subject to changes. That is not unreal, not unreal, but not absolutely real. Anything with changes you experience, you see it one way today and you see it different way tomorrow. Once we realize this presence, this presence of this reality within us, then we realize our eternal, immortal dimension.
