Manish, It is not clear as to if the observer in this case, was the main body or was not the main body, or was in a location other than the main body. Also please clarify the first part with the thoughts flowing. Is it that in your mind the thoughts can flow independent of the observing self? Will the thoughts continue to flow if the observing self is totally unaware of them, which would prove that they can flow even if there is no attention, not the slightest attention from the observing self? It is important to clarify this. Please do another meditation or more meditations if you need time to answer this.
