Think about it.

The five aggregates: also known as the five yins. "These are the five aggregates of form, feeling, thought, and awareness." There are five aggregates, namely, form aggregate, feeling aggregate, perception aggregate, formation aggregate, and consciousness aggregate. All dharmas, including the three periods of change and obstruction, near and far, good and bad, are all established as form aggregates. It is also necessary to understand the feeling aggregates and so on. Because of the accumulation of many dharmas, it is called the aggregate. (Excerpted from "Introduction to the Wise Man")

Things aggregate: It is a Dharma with current functions. All conditioned dharmas other than the other four aggregates belong to the formation aggregates. It includes all the mental states that correspond to the mental formations, the ropes that do not correspond to the formations, and all the non-corresponding formations. There are fifty-one types of mind. If the five views are counted separately, there are fifty-five types.

Feeling aggregate: having the appearance of understanding. There are three categories of feeling aggregates: painful feeling, pleasant feeling, and neutral feeling, or five types: pleasant feeling of body, pleasant feeling of mind, painful feeling of body, painful feeling of mind, and neutral feeling. From the perspective of dependence, it includes six kinds of feelings arising from the collective contact of the eyes, ears, nose, tongue, body, and mind. Each of these six kinds of feelings has three categories: painful, pleasant, and peaceful. In this way, there are eighteen kinds of feelings that are the proximate causes of the meaning of the mind. In addition, there are body feelings corresponding to the five sense consciousnesses and mental feelings corresponding to consciousness, loving feelings corresponding to craving for the body, unloving feelings not corresponding to love, craving and attachment feelings corresponding to craving for the five wonderful desires, and non-loving feelings corresponding to craving for the five wonderful desires. There are different differences such as attachment, detachment, and feeling.

Imagination aggregate: that is, attachment. If divided from the perspective of dependence, there are six types from the thoughts arising from the gathering of eyes and contact to the thoughts arising from the gathering of mind. Furthermore, if one clings to the appearance of external objects (righteousness) and clings to blue and yellow, etc., and clings to famous sayings, distinguishing between men and women, etc., the internal classification is equal to the number of the ten thousand dharmas known. It is also divided into the following six types: 1. Thoughts with forms: all thoughts other than those that do not understand the famous sayings, that is, although they see the material law but do not understand it because they are not familiar with the famous sayings, they are in the formless dharma realm and are neither thinking nor non-thinking. All thoughts; 2. Formless thoughts: thoughts that are not included in the form thought; 3. Narrow thoughts: Understanding all thoughts in the desire realm; 4. Vast thoughts: Understanding all thoughts in the form realm; 5. Infinite thoughts: Understanding The thought of knowing the boundless place of emptiness and the boundless place of consciousness; 6. The thought of nothingness: the thought of knowing the boundless place of nothingness.
