When you touch the lemon tree in early spring, you touch the lemons that will be there in three or four months. You can do that because the lemons are already there. You can touch the lemon tree in the historical dimension or the ultimate dimension; it is up to you. The practice of the Lotus Sutra is to touch yourself, the leaf, and the tree in the ultimate dimension.
