(8) The meaning of this section (18) is to call attention to the wrong paths of meditation so that one can enter the place of power instead of the cave of fantasy. This is the world of demons. This, for example, is the case if one sits down to meditate, and sees light lames or bright colours appear, or if one sees Bodhisatvas and gods approach, or any other similar fantasies. Or, if one is not * successful in uniting power and breathing, if the water of the kidneys cannot rise, but presses downward, the primordial power becomes cpld and the breathing heavy. Then the gentle light powers of the great Earth are too few, and the empty fantasyworld is entered. Or, when one has sat a long time, ideas rise up in crowds and one tries to stop them, but it cannot be done; one submits to being driven by them and feels easier. When this happens, one must under no circumstances go on with meditation but must get up and walk around a little while until heart and power are again in unison; only then can one return to meditation. In meditating, a man must have a sort of conscious intuition, so that he feels power and breathing unite in the field of the Elixir; he must feel that a warm release belonging to the true Light begins to stir dimly. Then he has found the right place. When this right place has been found, one is released from the danger of getting into the world of illusory desire or dark demons.
