So a literal reading is "Kitten Double Suicide" — which is not a common idiom.
The origins of Konekoshinji are rooted in the esoteric traditions of Shingon Buddhism, one of the main schools of Buddhism in Japan. Shingon Buddhism is known for its complex rituals, mandalas, and the invocation of various deities believed to embody different aspects of the Buddha's wisdom and compassion.
