For those familiar with the tree of life (and death)– they might also understand, albeit up to a certain degree or extent, how reality works. Nevertheless I’ll be explaining in a laymen-like manner how reality is configured.

Reality in the world/existence as we define it consists of the spiritual & the material- this is the bare bone, mundane description from the average person (I’m excluding those that don’t believe in the spiritual, e.g. science). The simplest way to go about it is as follows: Everything in reality starts at the divine, and then flows through most (at least) aspects of existence, then it reaches the spiritual & then manifests in the physical/material world.

Try moving your arm; what do you notice? You have to think about it, regardless of how swift & minor the thought. That thought is the spiritual as mentioned before. As is said and/or meant “It is from the immaterial that the material comes forth”. Even the word impulse is meant as a figure of speech, not literal, because impulsivity in this context is implausible. Doesn’t matter what physical action you undertake, you have to formulate the thought first. You’ll also notice that (according to this notion), important things you want to do e.g. go on vacation or buy a house requires a lot more in the way of thinking; you invest vast amounts of thought in accomplishing an objective.

For the rest, this doesn’t mean that every thought materializes- some thoughts get dismissed in a manner of speaking or lost in translation; that’s why you sometimes think about doing something & then change your mind at the last moment, although this applies more to superficial ventures rather than serious plans. The latter is more fixed due to its magnitude.
