Any purposive action has the intrinsic attributes of conviction and scope. Conviction expresses the intensity with which the purpose urges itself into action, or the belief in the reality of the stakes of the action, so that you could say that conviction has in turn the twin attributes of reality and stakes. Scope expresses the maturity of the purpose, its inclusiveness and resolution of alternate purposes and their concomitant actions, and is the product of the individual's entire history of experimentation with life. Your old friends Erfahrung and Erlebnis are perhaps relevant here, with Erlebnis being the dimension of experience belonging to conviction and Erfahrung that which belongs to scope. These concepts belong to experience as imbrication in the sense of understanding that no experience is isolated from the whole of Experience which recognises no spatial, temporal or personal boundaries. Any seemingly particular experience has implicit dimensions which are integral to its purposiveness and that overflow all conceptual boundaries. In so far as experience has resolved a greater portion of its implicit dimensions it has assumed greater scope, but there is no limit to how far this can go. And similarly in so far as the purpose in experience remains speculative and uncommitted, as its stakes are substitutable by alternatives, so is less real, less persuaded. But what this means is that while experiences may be found along a very wide scale of spirituality, from say self-serving and evil to self-sacrificing and divine, from the sleep of matter to cosmic-consciousness, the basic structure remains the same. No experience understood in this way can lead beyond the realm of experience itself. But the invariance of the structure is another sort of fact entirely, and it is the 'subject' corresponding to that invariance that you cannot do away with through any experience, no matter how expansive.
