People without plants are in a state of perpetual neurosis, a state of existential wanting.
Terence McKennaSince the very beginning of culture, what we seem to be are animals which take in raw material and excrete it imprinted with ideas.
Terence McKennaInwardness is the characteristic feature of the vegetable rather than the animal approach to existence. The animals move, migrate and swarm, while plants hold fast. Plants live in a dimension characterised by solid state, the fixed and the enduring. If there is movement in the consciousness of plants then it must be the movement of spirit and attention in the domain of vegetal imagination. (...) This is the truth that the shamans have always known and practiced. Awareness of the green side of mind was called Veriditas by the twelfth century visionary Hildegard Von Bingen.
