The Lotus Sūtra tells of a tortoise who lives at the bottom of the ocean and surfaces once in 3,000 years, finds a floating piece of sandalwood with a hole in it, and rests in the hole. This tortoise, moreover, is one-eyed and squints so it sees the west as the east, and the east as the west. It is likened to men and women who are born in the Latter Age of the Decadent Dharma; and the hole in the sandalwood is likened to the Lotus Sūtra and the “Namu Myōhō Renge Kyō.”
