Does the Buddha ever define "mind" ?

[sentinel]

If so , the arising of Misleading question then has to trace back and goes back to the text that illustrates there is a number six sense base !
If you tell any doctors or scientists there is a number six sense base sense medium or sense faculty called mind , all the laboratory equipment ,
the apparatus can't examine it right ?

They will be examining a certain functionality, and to do so, the word "mind" as a "noun" becomes needed (or functions as) to define the function to be examined.

Sorry , but the doctors and scientists examine the brains not the mind itself , perhaps psychologist will examine the "symptoms" of the Assuming mind .

[Bundokji]

Sorry , but the doctors and scientists examine the brains not the mind itself , perhaps psychologist will examine the "symptoms" of the Assuming mind .

They would still examine the brain as a functioning organ, and even if they divide it into different parts, they would be thinking of separate functions. Therefore, the name itself is a function "in disguise"
