Do you have any interest in the philosophies of introflection pioneered by Buddhism?

Buddhism is neat like that where you can just apply the philosophy without any deistic preferences.

Recently, just by chance, I was reading about a guy called Thomas Keating, who started what seems to be a Christianized version of Buddhist meditation.

Apparently there are also meditative practices in East Orthodox monasteries that closely resemble this, though I don't know if there's direct Buddhist influence there. 

Are these the kind of introspective practices you're thinking of here? 

I do think that making a habit of such meditation would be a really healthy thing to do. Unfortunately when I tried I was really bad at it. 

And as we can see, in the neoliberal bourgeois culture we have now, such practices can only be accepted if they are shown to have utilitarian therapeutic value. And then I think they have become something different from what they started out as.

Quite so, at least a good example, but we know Buddhism would focus on the Self over the Christianized God, I have a different form of meditation I practice, it works out pretty well for me.
