Knowing is mind, thinking is mind, feeling is mind, intention is mind. If you know these, you know the mind.
You can also know paying attention; paying attention is the mind. If you know looking and listening, they are also the mind.
You can experience these minds; you need to check for yourself.
You need to remind yourself ‘How do you feel? Are you aware? Are you thinking or aware?’ Slowly, you can be more familiar with the mind.
