I don't think you don't mistrust Islam as a concept.

I mistrust all concepts, in theory.

In fact, of course, I rely on concepts in daily life. In practice, I trust some. But they are all suspect, because, compared to the pure possibility of emptiness, they limit us. We trade that loss for utility.

Concepts are great! But the map is not the territory. If I want to know the territory, I have to experience the territory, any map will distract me. If I have chosen to travel from A to B, then a map can be very useful.

Ideally, I have the map, I can plot a course from A to B, but if I pass by C, of greater interest than B, I'll still see C, even if it's not on the map of All Places of Interest.

I think you tackle the concepts directly, rather than adding an extra barrier of "this is an abstracted ideology, I don't buy those".

It's more fundamental than that. I mistrust any interpretation. Abstracted ideologies are merely further from what I do trust, Reality. Sensory data is an aspect of reality. What that data can be made to mean is interpretation.

You call yourself a Muslim,

I wear a Muslim hat.

not an independent theologian with ideas from Islam.

I'm not a theologian, though I do think about what might be called theology. Islam, as I define it -- which happens to resemble the sources -- is not theology, though it has theological implications.

In many ways my approach is Buddhist, if one wants an "ism" to try to contain it.

Most of us are so distracted by words.
