Ryoan-ji (The Temple of the Dragon at Peace) is a Zen temple located in northwest Kyoto, Japan. In 1450, Hosokawa Katsumoto, another powerful warlord, acquired the land where the temple stood. He built his residence there, and founded a Zen temple, Ryoan-ji. During the Onin War between the clans, the temple was destroyed. Hosokawa Katsumoto died in 1473. In 1488, his son, Hosokawa Matsumoto, rebuilt the temple.
via Alma Kuzma "At Ryoan-ji in Kyoto there is a famous rock garden; wherever in it a person stands, one of the fifteen rocks cannot be seen. The garden reminds that always something unknowable is present, just beyond what can be perceived or comprehended - and that something is as much part of the real as any other stone amid the raked gravel." - Jane Hirshfield (from http://whiskeyriver.blogspot.com/)
