Higher ordination

Higher ordination (upasampadā, "full acceptance") is the formal ceremony that admits a person into the order of fully ordained monks or nuns. Buddhist monastic life usually comes in two steps: first a "going forth" as a novice, often quite young, then later this higher ordination, which confers full standing in the community along with all its responsibilities and the complete code of training rules. It is the threshold a person crosses to become, in the fullest sense, a monk (bhikkhu) or nun (bhikkhunī).

The ceremony is governed by the Vinaya, the body of monastic regulations the tradition traces to the Buddha himself. It is communal and procedural rather than mystical: a required number of already-ordained elders must be present, the candidate is formally questioned and presents the simple requisites of monastic life such as robes and an alms-bowl, and the assembly gives its assent through a set ritual of formal motion and agreement. Done correctly, this links every newly ordained monk or nun to a continuous line of ordinations reaching, in tradition's eyes, all the way back to the Buddha's first followers.

That lineage requirement matters enormously, because if a valid line of ordained elders dies out, it cannot simply be restarted by an individual. This is why the full ordination of women has been a live and sometimes painful issue: in several traditions the nuns' lineage lapsed long ago, and communities have debated how, or whether, it can be revived. Ordination is thus not merely a personal milestone but the mechanism by which the monastic community renews itself across the centuries.
