Some perceive this (eternal essence) as a wonder, and similarly indeed, others speak of it as a wonder; it is a wonder that some hear about this, and after hearing about it, some understand this and some do not.

Shri Krishna was getting ready to conclude the topic of the eternal essence. Therefore, he wanted to remind Arjuna about it, and also instill a sense of deep curiosity and interest in him. In this shloka, Shri Krishna did both of those things.

Four types of spiritual seekers are pointed out here. Firstly, there are seekers who have heard about the eternal essence through the Gita or through other means. Usually, most of them will hear about it and forget about it. But there will be some that will become interested in it, and will want to hear more – this is the second category. Of those seekers, some will try to gain an intellectual understanding about it and having done so, will be so enthralled with it that they will keep speaking about it to other people. This is the third category.

But the most devoted and advanced seekers will ultimately perceive the eternal essence directly, and the perception would have occurred without any sense organs. When this happens, there would be no words to describe it. The closest one could come to describing it is when we see something so wonderful that it renders us speechless, like a breathtaking painting or a waterfall.

Note that the meter has changed in this verse to indicate its importance.
