Thoughts are not the stuff that makes change. Nails, wood, hammers are. If you could make your thoughts like nails, wood and hammers no problem. You cannot train your mind because you aren’t separate from it, the mind is you (and there is no you). It’s sort of like E flat seems to be real and different from C#, but if you look at it from another angle they aren’t different plus they weren’t ever really here. Just like us, only appearing to be alive.
