釋禪波羅蜜次第法門 5.60

5.60

答曰：相兼故得爾。如熱是火體，兼水故有暖，兼風故有痒，兼地故有猗，兼三之時，失本熱相，故說有四。餘三大各兼三義，類此可知。復次，此十六觸各有十種功德善法，合則有一百六十法，而初坐發法之人未必發盡，或發三五，故略出之。

Answer: They are obtained thus because they combine with one another. For instance, heat is the essence of fire; combining with water, there is warmth; combining with wind, there is itching; combining with earth, there is peaceful ease. When combining with the three, it loses its original characteristic of heat; therefore, four are spoken of. The remaining three great elements each combine with three aspects, and can be understood by analogy with this. Furthermore, each of these sixteen sensations has ten kinds of meritorious wholesome dharmas, making one hundred and sixty dharmas in all. Yet a person whose dharmas arise in the initial sitting does not necessarily manifest all of them; some manifest three or five, which is why they are briefly set forth.
