Plants are more powerful than we generally believe. As macroscopic beings, they convey the cosmic light forces and enliven the earth's matter. All cultures, except our current one, are aware of the spiritual-soul dimensions of plants. In dreams or in the ecstatic vision of the shaman, plants appear as divine beings, Devas or light angels, who actively and consciously intervene in earthly events and human history. The book aims to be a step toward restoring the interrupted communication between humans and plants. An appendix with practical instructions for plant meditations facilitates contact with the plant devas.
