To become acquainted with plant spirits you need to exercise a great deal of patience.
Plants are stationary beings used to experiencing life at a very slow pace.
In order to get to know the plant spirits, sit down for hours with a particular plant, sensing it, talking with it, listening to it and just being with it. The plant may tell you what its properties are good for. Repeat the exercise as many times as you wish, until you begin to feel a spiritual communication with your plant. There is no single plant that represents the mystic world of creation, because creation is the sacred energy that moves through all plant life. The Great Spirit is part of every plant and none can be limited to any one form.
