When there is a pressure of the Force on the Adhar to work on it or enter, this [feeling of heaviness in the head] is often felt, especially if there is a working of the Force in the head. This heaviness disappears if the system receives and assimilates the Force and there is a free flow in the body – till then the pressure or some kind of heaviness is often felt at one centre or another where the Force is working.
