  The garden is cut off on the near side too, by a border of pebbles (larger, darker, and more rounded than the pieces of gravel) that runs along the east and north edges. There is a striking contrast between the severe rectangularity of the garden’s borders and the irregular natural forms of the rocks within them. The expanse of gravel is also cut through by the upthrust of the rocks from below: earth energies mounting and peaking in irruptions of stone. Each group of rocks is cut off from the others by the expanse of gravel, and the separation is enhanced by the “ripple” patterns in the raking that surrounds each group (and some individual rocks). And yet the overall effect of these cuttings is actually to intensify the invisible lines of connection among the rocks, whose interrelations exemplify the fundamental Buddhist insight of “dependent co-arising” (engi).
