Once we have practiced the stone and plant and animal excersises for a while we dont even need the objects to do the exercises, we just can conjure up animal , plant and stone feelings and colours out of these feelings and thoughts, organs of clairvoyance are formed.the spiritual eyes built up from observing the plants allows us to see soul and spirit colours. once we are able to see with spiritual eyes we are able to meet the higher beings. after illumination the soul unites with the spiritual world and is led to initiation.
