地论学派佛性论的“真如”与“真识”义

The Meaning of Thusness(Tatathat)and True Unsullied Consciousness in the Buddha-nature Theory of Dasabhumi-sastra School

通过对敦煌遗书中地论学派相关文献的梳理,结合隋代高僧净影慧远的著作,依“真如”与“真识”等核心概念剖析了地论学派佛性论的思想史脉络。这一思想的主要内容有以下几个方面:其一,以真如、法身等诠释佛性,以体用、隐显等探讨佛性的存在论与修道论;其二,以神虑、真心、真识心等诠释佛性,凸显佛性的主体意义,探讨佛性与佛身的因果意义,阐释佛性作为生死涅槃的同一体性,从而实现真理、本体与主体的统一。

This paper explores the intellectual sequence of Da's abhūmi-s stra School's theory of Buddha-nature with Thusness(Tatathat),true unsullied consciousness and other key concepts by investigating the texts of Da's abhūmi-s stra School in Dunhuang documents as well as the works of Huiyuan(523—592),an eminent monk in Jingying Temple in the Sui Dynasty(581—619).The main aspects of this theory are as follows:First,it interprets Buddha-nature through the concepts of Thusness and the embodiment of truth and law(buddhakaya)and discusses the doctrine of existence and cultivation methodology of Buddha-nature with the concepts of ti(substance)and yong(function),yin(concealing)and xian(revealing);second,it interprets Buddha-nature with the concepts of Buddha's spirit,true Buddha-mind,and true unsullied consciousness,highlighting the subject state of Buddha-nature.This paper also explores the causality between Buddha-nature and Buddha-embodiment(buddhakaya),showing the identical Buddha-nature in both reincarnation and nirvana.In this way,truth,substance and the subject are unified.
