集異門論七卷二頁云：四處者：一、慧處，二、諦處，三、捨處，四、寂靜處。慧處云何？答：如薄伽梵於辯六界記別經中為具壽池堅說：苾芻當知最勝慧處，謂漏盡智。是故苾芻應成就漏盡智。若成就漏盡智，說名成就最勝慧處，是名慧。諦處云何？答：如薄伽梵於辯六界記別經中為具壽池堅說：苾芻當知最勝諦處，謂不動解脫。諦者。謂如實法。誑者。謂虛妄法。是故苾芻應成就不動解脫。若成就不動解脫，說名成就最勝諦處。是名諦處。捨處云何？答：如薄伽梵於辯六界記別經中為具壽池堅說：苾芻當知，先所執受無智無明，越正路法；今時應捨、應變吐、應除棄。苾芻當知，最勝捨處，謂棄捨一切依，愛盡離染，永滅涅槃。是故苾芻應成就此涅槃。若成就此涅槃，說名成就最勝捨處，是名捨處。寂靜處云何？答：如薄伽梵於辯六界記別經中為具壽池堅說：苾芻當知貪染惱心令不解脫，瞋染惱心令不解脫，癡染惱心令不解脫。苾芻當知。此貪瞋癡無餘永斷，變吐除棄，愛盡離染永滅靜沒，名真寂靜。是故苾芻應成就真寂靜。若成就真寂靜，說名成就最勝寂靜處，是名寂靜處。
