首楞嚴義疏注經 8.587

8.587

無心於境，境自橫來，境自有心，己何所味，故云味如嚼蠟等。以樂變化五欲之境而受用故。

Having no mind toward the sense objects, the objects present themselves spontaneously; the objects themselves have desire, but oneself feels no taste in them—hence it is said, "it tastes like chewing wax," and so forth. It is named because they delight in transforming the realms of the five desires to partake of them.
