The reason why I could not solve it is that I didn’t understand what the question was asking. Therefore, I approached this topic to find some connections between distorted sañña belonging to uppatti bhavanga and the mechanism of the information transfer system from physical body to manomaya kaya. I only thought about sañña as a form, not as a content like mother sañña, chocolate sañña or anicca sañña. The explanation is enough to know it for me.
And while solving this problem, I learned that the sanna can be analyzed into form and content.
For example, I understand sañña as below. The three general types of content of sañña.
First is the value(the usage of mathematics or physics) of something, like the shape value(round, squared, etc), sound value(high tone, low voice, etc.), and so on.
Second is recognition of something. Using the first type of sanna, one can distinguish things like ‘this is a car, that is a rose‘. So naming or chunking of information is within sanna’s work.
Third is the value(worth) of something. Like anicca sañña or nicca sañña. This type of sañña is related with the way one deals with the first and second type of sañña, but not the content of them.
The sanna we should cultivate is the third type. Distorted sañña is only about the first and second type. We have to do nothing about them. But we only have to cultivate anicca sañña. This is why arahant do things without defilement even if they still have distorted sañña.
The only important content of sañña is the third type. So we try to question to find out what is the best way to value something correctly. That is the whole purpose of vipassana bhavana.
