To stop abruptly activities, movements, thoughts and hold one's mind in a state of suspense, yet relaxed, is another exercise if the relaxation is passive enough. It leads into a meditative mood or a glimpse. Useful exercises are to concentrate consciousness on the point between the eyebrows or in the heart centre or in the centre behind the solar plexus. These are of course only yogic exercises, but useful as preparatory ones. More important is the attempt to put his own person into a new perspective, to transcend his own ego from the Overself plane.
