So far, Shri Krishna was talking about the process of meditation, what should be the meditator’s approach, how should he sit and so on. But having come out of meditation, what is the vision of the perfected meditator?
 
Shri Krishna says that the perfected meditator sees his self in all beings, and all beings in his self. It is difficult to comprehend what this means without actually practising meditation. We can do our best to understand it through an example.
 
We will use the illustration of the wave and the ocean as our running example. As an individual, we have a name and a form. In the same way, we can assume that each wave in the ocean has a (fictitious) name and form. If we go with this analogy, then we can consider ourself as one of those waves.
 
Meditation enables us to expand the notion of what a wave is. So first, we begin to see that although there are different kinds of waves in the ocean, in essence, they are nothing but name and form. Some waves are big, some are small. Some last for a few seconds, some last for much longer than that. Now I could be a small wave and you could be a big wave, but both of us are waves nevertheless. It is akin to realizing that we are all in the same family, company, nation and so on.
 
This stage of the perfected meditator’s vision is indicated by the words “he sees his self in all beings”.
 
As we further expand our vision, we begin to unravel the base of all these waves. We think: yes, all of us are waves, but what holds us together? We then realize that all waves no matter how big or small are contained in the ocean. The ocean is infinitely larger than all of the waves put together. None of the waves can exist without the ocean.
 
The final stage of this vision is reached when we as the wave realize that the ocean also is a name and form, even though it is infinitely larger than all of the waves put together. At its essence, it is nothing but water. I am the wave is water, other waves are water, the ocean is also water.
 
This state is indicated by the words “he sees all beings in his own self”, and such a person is called "sarvatra samadarshanaha", one with equal vision.
 
Another point made in this shloka is that this “seeing” does not happen just with one’s eyes. This vision comes out of wisdom. Such vision is sometimes referred to as the “third eye”. This is the vision of a “sthitaprajnya” that was briefly discussed in the second chapter.
 
This topic is further elaborated upon in the next few shlokas.
