They are fed by the three qualities, and their tender shoots are the sense objects that tempt the mind. A second set of roots grows down into the human world, and these roots are tied to action (karma). The point is that human life is where the tree is most firmly anchored, because here actions done with desire create further ties. The tree is not only out there; it grows through our choices.
