The paper offers a critical appreciation of sand in the Japanese tradition of karesansui 枯山水gardens. At first, sand is approached from a phenomenological standpoint, then described in relation to the Daoist ideals of “blandness” (dan 淡) and its original function in Shinto shrines. The following sections draw an East-West comparison between the sand garden at Ginkaku-ji 銀閣寺 and the sand sculptures by the Basque artist Andoni Bastarrika, and between the sand garden at Shisen-dō 詩仙堂 and the Renaissance garden at Villa di Castello. The main purpose is to illustrate the philosophical significance of sand in respect to the aesthetic expression of such Buddhist-influenced notions as ku 空 (“emptiness”), yuge 遊戲(“play”), kire-tsuzuki 切れ続き(“cut-continuance” or “dis/continuity”) and the dialectic of conventional and ultimate reality.
