Gesshu SokoPer the Treeleaf 'Our Lineage' page, the Hōzōji abbot lineage descends from Gesshū Sōko (1618–1696) — the same Edo-period Sōtō master who taught Tenkei Denson in a parallel branch. Tokuzui Tenrin appears in the Treeleaf-charted chain immediately after Gesshū in the Hōzōji sequence (note: this connection is inferred from sequential numbering in the Treeleaf lineage and may benefit from primary-source verification — a future Japanese-language pass could confirm or correct it). · 1618 – 1696
