What helps me develop spiritually (i.e. become less deluded) lately is a more rational approach. This paper gives a very interesting and rational analysis of what awakening is: [www.researchgate.net
A model is presented of awakening experiences that postulates 3 layers of processing, sensory, perceptual, and cognitive, that separate external energy from awareness. The model hypothesizes that awakening experiences results from the progressive removal of the cognitive, perceptual, and sensory layers of information processing. This to some extent returns awareness to a primal state that was present before the development of neural information processing.
Reality is whole and undivided. Ego and its perceived reality consisting of separate parts are the result of the cognitive and perceptual layers of processing, opaquely overlaying the direct experience of actual reality. During an awakening experience, these layers are temporarily inhibited so that you experience reality more directly. But as soon as those layers of processing kick in again, ego returns—the experienced reality is again one consisting of labels, comparisons, judgments, segregation, etc.
The ego that was relegated to the background during the awakening experience now comes back into the foreground and takes credit for the experience, thinking that "I am awakened," while the awakening was in fact the absence of that very I.
So the challenge after an awakening experience is to not get stuck in the spiritual-ego phase, in which one is still very deluded and prone to zealotry and grandiosity. Most "spiritual leaders" seem to be stuck in this phase.
The awakening becomes more permanent when our convictions, our conceptual take on reality, get seen through. Then the perceptual and cognitive layers of processing become transparent, so that the underlying beauty and wholeness/holiness of actual reality can shine through.
This probably won't happen unless seeing reality as it is becomes one's number one priority. It takes loving devotion, child-like curiosity, radical self-honesty, and independent thinking. The latter is very important because if our thinking follows the societal norm, we'll stay deluded (which is the societal norm). We need to stay away from group-think, and that includes any spiritual group-think.
