大般涅槃經集解 52.6

52.6

案僧亮曰：小乘厭苦，除斷五陰也。寶亮曰：既依六行，理以忘懷，亦無有善。而不樹故，積劫為心師，要依此理教而得出也。是以始學之家，先觀五陰為本。既達身是虛，必修善而斷，故今先觀五陰為始也。受有百八者，此是一方之數。受是三受，三受有二種，謂淨受不淨受。就六根中作位，兩受皆然，則一根中有六。若六根具六，便六六三十六。就三世中往分，便成百八受。

Sengliang states: In the Hīnayāna, one loathes suffering and severs the five aggregates. Baoliang states: Having relied on the six practices, in principle one puts all mental clinging out of mind, and there is also no good that is not planted. Therefore, having taken the mind as teacher across accumulated kalpas, one must rely on this principle and teaching to escape. For this reason, beginners first contemplate the five aggregates as the foundation. Having understood that the body is illusory, they will certainly cultivate good and sever [afflictions]; hence now one begins by contemplating the five aggregates. Regarding the hundred and eight feelings, this is a method of reckoning. Feeling comprises the three feelings, and the three feelings are of two kinds: pure feeling and impure feeling. When classified among the six sense faculties, both feelings apply alike, so within one faculty there are six. If each of the six faculties possesses six, then six times six makes thirty-six. When divided across the three time periods, they become one hundred and eight feelings.
