Ariadna Dōsei Labbate

Ariadna Dōsei Labbate (born 1969 in Argentina)^[1] is an Argentine Sōtō Zen nun in the Deshimaru–Kōsen line and the resident teacher of the Templo Zen Shōbōgenji at Capilla del Monte in the province of Córdoba^[1] — the temple Stéphane Kōsen Thibaut founded in 1999 as the first Sōtō Zen temple in South America.

She began zazen in 1988 within the Asociación Zen de América Latina, the Latin-American branch of the Kosen Sangha founded by Thibaut^[1], and was ordained as a Zen nun in February 1992^[1]. For more than two decades she served as Kōsen's secretary and translator, accompanying him on his trans-Atlantic missionary trips and founding satellite practice centres in Uruguay and Argentina^[1].

In April 2015 she received shihō from Kōsen Thibaut, becoming "the first woman zen master in this Buddhist school in Argentina"^[1] — a description preserved in the Buddhistdoor en Español interview-profile of her practice^[1] and corroborated by the official Kōsen Sangha shihō roster, which lists her among the 2015 cohort alongside Igelnick, Julien, and Femenias^[2]. She remains the responsible teacher of Shōbōgenji and dedicates her work to spreading Zen practice through teisho and sesshin across the Hispanophone Americas^[1].
