妙法蓮華經玄義 1.66

1.66

譬喻者，譬如總名人身，開身則有識、命、煖，分別諸身貴、賤、賢、愚，種種差降。人身譬名，識以譬體，命以譬宗，煖以譬用，分別譬教相（云云）。

As for analogies: it is like generally naming the human body; analyzing the body reveals consciousness, life-force, and warmth; differentiating various bodies reveals noble, base, worthy, and foolish, with varied gradations. The human body is an analogy for the title; consciousness serves as an analogy for the substance; life-force serves as an analogy for the central purport; warmth serves as an analogy for the function; and differentiating [them] serves as an analogy for the classification of teachings (and so forth).
