Grammatical Analysis
Satthā: [m.] Teacher; Master. Derived from root sās (to teach, instruct, rule). Nominative singular of satthar (Sanskrit: Śāstṛ).
Orthodox Definition
In the Pali Canon, Satthā is the primary epithet used by disciples to refer to the Buddha in his capacity as a guide. When listing the nine supreme qualities of the Buddha (Buddhānussati), he is specifically called “Satthā devamanussānaṃ” — the Teacher of devas (gods) and human beings.
This title emphasizes the Buddha’s role not as a creator, a savior who grants grace, or a prophet relaying a divine message, but strictly as an unparalleled pedagogical master. He is the shower of the way (maggakkhāyī). He provides the exact instructions required to escape saṃsāra, but the effort to walk the path remains entirely on the shoulders of the disciple.
As noted, upon his passing, the role of the Satthā was officially transferred to the Dhamma-vinaya.
