The correct way of practice is to simply sit in stillness and silently investigate; deep down there is a state one reaches where externally one is no longer swirled about by causes and conditions. The mind being empty, it is all-embracing; its luminosity being wondrous, it is precisely apt and impartial. Internally there are no thoughts of grasping after things; vast and removed, being just as it is - free from confusion. Alive and potent, all dependency and opposition are severed; one remains self-contained.
