The Dilun zong: in English， the Stages Sect， or School of the Treatise on the Bhu^mis. One of the earlier schools of Chinese Buddhism， which was based on the commentary written by Vasubandhu 世亲 on the Da/sabhu^mika-/sa^stra （Shidijing lun 十地经论）， which also forms the commentary on one chapter of the Huayan jing华严经. Ratnamati勒那摩提 and Bodhiruci 菩提流支 brought the manuscript of the Da/sabhu^mi-vya^khya^na and translated it into Chinese during the Northern Wei dynasty. The Dilun school was based primarily on Yoga^ca^ra philosophy 瑜伽行派， particularly theories of the a^layavijn~a^na 阿赖耶识. The northern branch of the school， represented by Bodhiruci's student Daochong 道宠， took the position that the storehouse consciousness is not real， and that buddha-nature is first acquired on attaining buddhahood， thus it is not inborn. The southern school， represented by Ratnamati's student Huiguang 慧光， saw the a^layavijn~a^na as real and identical with the inborn buddha-nature佛性. The Huayan school华严宗 is said to have developed out of the southern branch， while Faxiang 法相宗absorbed the northern branch.
