瑜伽論記 6.72

6.72

景云：惡趣苦為一，生老病死苦又為四，足前為五，愛別離苦為第六，自業所作一切苦因第七。前之三苦各分二為六，自業所作故一切苦因之所隨逐合為一相，即成七相。

Jing says: 'The suffering of the bad destinies is one; the suffering of birth, aging, sickness, and death are another four, which added to the former make five; the suffering of separation from what is loved is the sixth; all causes of suffering created by one's own karma are the seventh. The former three sufferings are each divided into two, making six; being created by one's own karma, being pursued by all causes of suffering is combined as one mark, thus making seven marks.'
