Above that is the “plant” aspect, the second aspect of the desire to receive. It is a greater aspect than that of the inanimate, and the desire to receive dominates each and every individual [not just the species]. Each individual [plant] moves independently, as it spreads out near and far to follow the sun. Individual [plants] also have the need for food and drink, as well as the need to excrete. Still, they do not contain individual feelings.
Desire to Receive Grows from Mineral to Human
