That said, I am not sure I understand what you mean when you say "cravings and aversion come from how you react to things you may find desirable or undesirable". It seems kinda meaningless, like yeah, I feel aversion when I don't want things to happen and yes, things I don't want to happen are undesirable to me. And yes, desirableness and undesirableness are, of course, connected to me, it is me who decides which things are desirable or undesirable to me.
Like, lets say I fall into sewage treatment tank. Drowning in shit is an undesirable thing and I feel a great aversion to it. And yes, it is me, personally, who finds drowning in shit undesirable, the undesirableness of this outcome is connected to me very directly. But I do not see how meditation might help me.
