lit. 'who has entered the lineage (of the Noble Ones)', i.e. the Matured One.
I. 'Maturity-Moment' (gotrabhū-citta) is the last of the 4 impulsive moments (javana, q.v.; cf. viññāna-kicca) immediately preceding the entering into an absorption (jhāna, q.v.) or into one of the supermundane paths (s. ariya-puggala, A.). Cf. visuddhi VII.
II. The 'Matured One'. "He who is endowed with those things, immediately upon which follows the entrance into the noble path (ariya-magga), this person is called a 'Matured One'." (Pug 10). In the Com. to this passage it is said: "He who through perceiving Nibbāna, leaves behind the whole multitude of worldlings (puthujjana, q.v.), the family of worldlings, the circle of worldlings, the designation of a worldling and enters into the multitude of the Noble Ones, the family of the Noble Ones, the circle of the Noble Ones, and obtains the designation of a Noble One, such a being is called a Matured One." By this state of consciousness is meant the lightning-like transitional stage between the state of a worldling and that of a Sotāpanna; s. ariya-puggala. - Gotrabhū is mentioned in this sense, i.e. as 9th ariyapuggala (q.v.), in A.IX.10; A.X.16.
