Roshi

Roshi is an honorific for a senior Zen teacher, literally old master, and what matters in the tradition is not the title but what stands behind it, the transmission of the dharma from master to master.

The word and the reality

The title is given to a venerable Zen teacher, and its literal sense of old master conveys the respect due to age and attainment, but the substance to which it points is dharma transmission, the formal recognition by a master that a disciple has realised the teaching and is authorised to teach in turn, which is the true mark of authority in Zen. A roshi is properly one who has received such transmission and guides students, so the honorific rides on the transmission rather than replacing it.

Lineage and its verification

Dharma transmission places the teacher in a lineage reaching back, in the tradition account, through the Zen patriarchs to the Buddha, and it is this line of mind-to-mind transmission, verified by a recognised master, that the tradition treats as the guarantee of a teacher authority, more than any examination or institutional appointment. The reliance on personal transmission has also made the verification of a teacher standing a live concern, especially as Zen has spread to the West, where questions of who holds genuine transmission have arisen. The title roshi thus points beyond itself to the central Zen claim that the teaching is carried from awakened mind to awakened mind, and that a true teacher is one so recognised within a lineage.

Zen reached a wide Western audience first through the scholar D.T. Suzuki, whose English writings and lectures from the early twentieth century introduced Zen philosophy to American and European readers well before any resident teacher arrived to found a training centre, and the practical transmission of the roshi role to the West followed a generation later, when teachers such as Shunryu Suzuki, who founded the San Francisco Zen Center after emigrating in 1959, and other Japanese and Korean teachers established the first Zen training centres in North America to actually ordain and train Western students under a resident roshi.

The Zen that resulted in the West is not one lineage but several operating side by side, Soto and Rinzai teachers from Japan, Seon teachers from Korea, and Western-born roshis who received transmission from these founding generations and now lead their own independent centres, each maintaining its own standards for when a student is authorised to be called roshi in turn. That plurality means there is no single body that certifies the title across Western Zen as a whole, and a student encountering the honorific has to look to the specific lineage and teacher behind it rather than to any general standard the word roshi guarantees on its own.
