I think I can give you a direction to consider that might shed some light on this conundrum. I’m not great at explaining this, but I’ll give it a shot.
We all know that the five khandas are impermanent, not self, a barb, a canker. We also know that the trajectory of the N8FP is to understand the 5 khandas for what they are, to purify the mind and develop wisdom. So on one hand we have the khnada consciousness/vinnana (the faculty of knowing) and on the other hand we have the mind, which knows, that we need to purify. How to separate these two?
MN 43 solved this for me:
“They speak of ‘consciousness’. How is consciousness defined?”
“It’s called consciousness because it cognizes. And what does it cognize? It cognizes ‘pleasure’ and ‘pain’ and ‘neutral’. It’s called consciousness because it cognizes.”
“Wisdom and consciousness—are these things mixed or separate? And can we completely disentangle them so as to describe the difference between them?”
“Wisdom and consciousness—these things are mixed, not separate. And you can never completely disentangle them so as to describe the difference between them. For you understand what you cognize, and you cognize what you understand. That’s why these things are mixed, not separate. And you can never completely disentangle them so as to describe the difference between them.”
“Wisdom and consciousness—what is the difference between these things that are mixed, not separate?”
“The difference between these things is that wisdom should be developed, while consciousness should be completely understood.”
The khanda vinnana is the untrained mind which knows that which is the product of the processes of the khandas. Wisdom is the outcome of a purifying mind. The khanda consciousness should be completely understood, wisdom should be developed.
MN 13 describes the five cords of sensory pleasure:
And what is the gratification of sensual pleasures? There are these five kinds of sensual stimulation. What five? Sights known by the eye, which are likable, desirable, agreeable, pleasant, sensual, and arousing. Sounds known by the ear … Smells known by the nose … Tastes known by the tongue … Touches known by the body, which are likable, desirable, agreeable, pleasant, sensual, and arousing. These are the five kinds of sensual stimulation. The pleasure and happiness that arise from these five kinds of sensual stimulation: this is the gratification of sensual pleasures.
The mind is not included as a sensory pleasure. It’s not a danger, is not something to get rid of but rather something to develop via the N8FP, brahmaviharas, jhana, joy, wisdom. The untrained mind of consciousness needs to be completely understood, and wisdom and Right View needs to be developed.
So an ordinary, unlearned person operates out of the khandas, and a wise person operates out of a purified mind.
