补充资料:减缘减行
【减缘减行】
 (术语)缘者,指上界四谛与上二界四谛之八谛。行者,指欲界四谛下十六行相与上二界四谛下十六行相之三十二行相。自声闻乘四善根之初至忍法之上忍,连环普观此上下八谛之三十二行相,同自中忍之位,一行减之,遂至留苦或道等之一行相,谓之减行,每减其四行相自减一谛,故谓之减缘。其所以减之者,泛观上下八谛之三十二行相,观智浮漫而不猛利,故自中忍以后渐渐狭其观境,以养成猛利之观智,遂为发真无漏智之算引也。上下八谛之三十二行相,第一回自第一观至第三十一,因而减去第三十二即上界道谛下出之一行相,第二回更自第一观至第三十,因而减去第三十一即上界道谛下行之一行相。如此每一周自下逆次减一行相,终至减第一即欲界苦谛下苦之一行相。即减去者,三十一行相也。减此三十一行相中,每第四周减一谛,故谓之减缘,减于他三周之行相,谓之减行。即减缘七周,减行二十四周,合于三十一周减去三十一行也。第四周谓之减缘者,上下八谛,为所缘之境,三十二行相,为对于此之能缘观解,故减四行相即减所缘之境一谛也。因而逆次减去,每至第四行相,不谓为减行,特附以所谓减缘即减谛之名耳。(参见:行相)
