Your experiences, your inclinations and motives, all that is the movement of the past, which is knowledge. Movement of the past can only take place through knowledge, which is the past. So the past interferes with the present; the observer comes into operation. If there is no interference, there is no observer, there is only observation.

. . . 

In observation there is neither the observer nor the idea of observation. This is very important to understand. There is no observer or the idea of not having an observer. Which means there is only pure observation, without the word, without the recollection and association of the past. There is nothing, only observation.
