Basically we are emotional ,these emotions mix and color mostly all we do ,the observer can see apprehend this more clearly instead of being carried away via its patterning .
The observer can more easily spot the rise of each type of emotion and the decline ,but not the death ,because it will surely return either sooner or later .
Lots of different methodologies ,or advice attempt to change these patterns to a ideal , the observer is different ,no attempt is made to change ,only to observe yet paradoxically understanding grows in the observer that the colors present in those emotions would thwart the too early implementation of real change .
So we would need to know what constitues real change? ,and on the route to change the observer will aquire two important elements out of the struggle to observe one is understanding and the other is purification ,the observer as understanding and some purification ,these two elements are indispensible .
