Theravāda Buddhism

Definitions: - I want to emphasize the mind, the body doesn't ache, isn't sore, isn't itchy, nothing at all; that is the 'an lạc' of the body (bodily ease/well-being). - 'Thanh thản' (serenity) is when our mind doesn't ponder, isn't busy at all; that is 'thanh thản'. - 'Vô sự' (actionlessness/nothing-to-do) is doing nothing at all; the body also does nothing, and the mind also doesn't ponder, meaning it does nothing; that is 'vô sự'. It is normal, very normal like a normal person, yet doing nothing at all. That is: the head/mind doesn't work, and the hands and feet also don't work; that is 'vô sự'. As for the mind that doesn't ponder, doesn't worry about anything at all, that is 'thanh thản' (serenity). As for the body that doesn't ache, isn't sore, itchy, nothing at all, that is 'an lạc' (ease); it is normal. Just like right now, [if] our body has no aches or pains, that is the 'an lạc' of our body. That is the state right now; it's not anything strange or different. It is the normalcy of a normal human being. Therefore, once you recognize that normalcy, now you just need to use the method of Right Thinking (Như Lý Tác Ý), guide it [the mind]: > "A mind unshaken, serene, at ease, and free from involvement.” You just fear it [the mind] will move and ponder about this and that, so you remind it: ‘Mind immovable, serene, at ease, actionless,’ and then just sit relaxedly/idly like that. So, can I use "unshaken, serene, at ease, uninvolved" as a mindful reminder throughout my day to make my mind feel better?
