साहू साहुणी सावया य, सावियाओ चउव्विहो संघो ॥२०.१॥
Monks, nuns, laymen, and laywomen — the community is fourfold.
The opening sutra establishes the structural architecture of the Jain community with elegant economy: monks, nuns, laymen, laywomen — four orders, one community. The Chaturvidha Sangha — literally "the fourfold community" — is one of the Jain tradition's most distinctive social and theological achievements. Unlike many religious traditions that reserve full spiritual participation for a single ordained class (the priests, the brahmin scholars, the male monks), Jainism explicitly includes four distinct orders, each with its own role, its own appropriate vows, and its own genuine path toward liberation. This is not merely organizational diversity. It reflects a deep theological commitment: the teaching is for everyone. Not for a spiritual elite who happen to have the right birth or gender or resources to become monks. The fourfold structure means that the teaching is embedded in a complete social reality — it lives in the monastery and in the household kitchen, in the monk's begging round and in the layperson's business ethics. It is a practice for all of human life.
The simple version: The Jain community has four orders, not one. Everyone has a place, a role, and a path — not just the monks.
