During World War II, separated by geographical and political gulfs, two of our esteemed Dharma ancestors, Soen Nakagawa Roshi and Ven. Nyogen Senzaki, exchanged Dharma greetings each month. These great teachers shared in chanting, zazen, and prostrations across the Pacific Ocean.

We uphold this Mandala Day tradition each month, celebrating simultaneously at New York Zendo Shobo-ji and Dai Bosatsu Zendo. This special chanting ceremony commemorates and pays homage to the predecessors in our lineage and all related teachers, known and unknown, who helped to further the Buddha-Dharma.

Mandala Day is celebrated at Shobo-ji on the Wednesday closest to the 21st of each month. Refer to the calendar for exact dates. If attending, please wear tabi or clean white socks to the zendo. There will be one period of zazen before chanting, and a short period of zazen will follow.
