Who thus know, by the eye of knowledge, the difference between kṣetra and kṣetrajña, and the dissolution of the prakṛti of beings, they go to the supreme.

In plain words
This verse is here to gather up everything the chapter has said.
By the eye of knowledge — the knowledge about the Self itself, born from instruction given out of the grace of scripture and teacher — a person comes to see the real difference between the field and the field's knower, exactly as it has already been explained. And with that same eye, they also come to see beings released from their own prakṛti — prakṛti, that ignorance-natured thing also called 'the unmanifest' — released, meaning it simply ceases to hold them any longer. Whoever truly knows both of these things — the difference between field and field-knower, and this release from prakṛti — such a person goes straight to the highest reality, the Supreme Self, Brahman itself. They never take up a body again. That is the meaning.
Close to the Sanskrit
This verse has for its purpose the gathering up of the meaning of the entire chapter.
The difference — the particular mutual distinctness — between kṣetra and kṣetrajña, as already explained, in the manner already shown, by the eye of knowledge — that eye being the knowledge pertaining to the Self, born from the instruction given through the grace of scripture and teacher — by that eye of knowledge, and the release of beings from their own prakṛti — the prakṛti of beings, characterized by ignorance, called the unmanifest — the release from that prakṛti of beings, that is, its going to non-existence — whoever knows, fully understands, these two things: they go, they proceed, to the supreme reality that is the Supreme Self, Brahman; they do not take up a body again: that is the meaning.
