How to relax the mind before doing the concentration practices?
I've read lots of lectures, yet I lack understanding what is true relaxation of the mind.
At first I relax body, then start to observe mind. To begin with loudly (in mind) identifying every thought I see.
However after some time state of perception changes and observer starts receiving various chaotic experiences from the mind. Shortly afterwards observer sinks into mind and loses separation between observer and thing observed. And starts dreaming...
Am I doing it right? How should I maintain separation and do not identify?
