Clinging to perception aggregate

S 14.7 The Discourse on the Diversity of Perception says this: > Dependent on the mind-object element, there arises the perception of > mind-object; Dependent on the perception of mind-object, there arises > the thought regarding mind-object; Dependent on the thought regarding > mind-object, there arises the desire for mind-object; Dependent on the > desire for mind-object, there arises the passion for mind-object;Dependent on the passion for mind-object, there arises the searching for mind-object. i want to know if clinging to perception aggregate is causing thinking to occur. i am not interested in thinking (sometimes, more than not, interal verbalization). it's unhappy, tiresome, stressful, etc. if so, how am i clinging to perception aggregate? i am not aware of clinging to this...is it an unknown mind- object? can knowledge be a mind-object?
