6.87

答曰：「一時得二種戒，得優婆塞戒，得沙彌戒。若不受五戒、十戒，直受具戒，一時得三種戒。」

He replied, “They obtain two kinds of precepts all at once: they obtain the upāsaka precepts and obtain the śrāmaṇera precepts. If they do not receive the five precepts or the ten precepts, but directly receive the complete precepts, they obtain all three kinds of precepts all at once.”
