Ruben L.F. Habito (born c. 1947) is a Filipino former Jesuit priest turned master practicing in the Sanbo Kyodan lineage of Zen. In his early youth he was sent to Japan on missionary work where he began Zen practice under Yamada Koun-roshi, a Zen master who taught many Christians students, which was unusual for the time. In 1988, Ruben received Dharma transmission from Yamada Koun. Ruben left the Jesuit order in 1989, and in 1991 founded the lay organization Maria Kannon Zen Center in Dallas, Texas. He has taught at Perkins School of Theology, Southern Methodist University since 1989 where he continues to be a faculty member. He is married and has two sons.
