Passively to observe and feel the past´s activity is an act without past

When the Taoist monk is sitting and observing a tree passively without any kind of thought-activity, then it is an act, which isn´t defined by the past.

And passively to observe and feel the past´s activity is also an act without past.

To be the past present is to be one with your past, without that there is any displacement or distortions between the realizer and the realized.
