besetting

The act of one who besets or attacks.

I might also here tell you of the contests and battles that such are engaged in, wherein they find the besettings of Satan, above any other of the saints.

Deeply rooted; persistent.

The first thing to bear in mind (especially if we ourselves belong to the clerico-academic-scientific type, the officially and conventionally “correct” type, “the deadly respectable” type, for which to ignore others is a besetting temptation) is that nothing can be more stupid than to bar out phenomena from our notice, merely because we are incapable of taking part in anything like them ourselves.

Rickie would not push himself. It was his besetting sin.

Obsessive

Neither were they connected with fear: he was conscious of no fear. Rather, they originated in a strange besetting desire to know what to do when the time came; a desire gigantically disproportionate to the few swift moments to which it referred; a wondering that was more like the wondering of some other spirit within his, than his own.
