...it describes a way as your concentration deepens by doing passion meditation
as your concentration gets more laser-like, your awareness stands back from time, you get to the point when in a very deep meditation you begin to see your own thoughts arsing and existing and passing away, about one trillion per blink of an eye. so if you were to stand back far enough to see a thought come in existence, exist and pass away - it means you gotten your mind very far back in relation to time.
...as you get to the point, where thought comes into existence, exists and passes away, between that thought and the beginning of the next one there is space, and if you enter that space, you are known as a stream-enterer, and that is entering into what is called as nirvana, which is the feel behind the form, or a feel that is inherent in the form, or feel out of which form arises.
