Numbers are always an interesting topic. Number have told us a great deal about 'secrets'. Pythagoras delved into numbers to find meaning to union, love, beauty, perfection and manifestation. There is gnosticism in the agnostic nature of numbers. Numbers are bare apparent, yet are also apparently mysterious.
As above so below. The hidden, the manifest, the first and the last are all one. The father, the son and thw holy spirit are one. Yet while 'He' encapsulates all, he is none of them singularly. They are merely faces/modes of 'he'.
Lets look at a projector doing its job. The image on the screen is the son, the beams of light from the projector is the holy ghost, and the image in the projector is the father. Yet he is not any of them, he is the essence of each. Not the projector, not the screen and not the light individually. These are all faces that bring to light the inseparable unified essence. He is the fourth and the zero.
As above so below, as inside so too outside. Most time it is hard to discern our internal condition. Yet there is a very simple way, observe the external. Starting to see things, faces, numbers, within other things means that internally, we are starting to 'see' meaning within meaning. When I say starting, I mean that the process has started, has nit yet completed and is still moving towards completion. Once the process completes, there should have access to deeper insight. There should be an ability to read between the letters. A more complete understanding, a more direct understanding. As far as the process goes, there really is no worry, it will complete by itself. The only thing we need to concern ourselves with is that we are comfortable as the process unfolds. I think for you, hop-daddy, this is not a problem since you already understand the importance of fundamentals. Here fundamentals means grounding and cleaning.
One other thing that I'd like to take this chance to talk a bit about is the difference of energy between the lower chakras and upper chakras. The upper chakras use energy in forms finer and more subtle than the lower chakras. The heart chakra is where energy is refined for use by the upper chakras. It is possible to force-feed the upper chakras with coarser energy, this however will have detrimental side effects. What this means is that it is possible to turbo-boost clairvoyance, yet it will have side effects. The proper way is to refine energy, creating a supply of finer energy, suitable for higher chakra use, and ground the excess. In the seven chakra system, the heart chakra is the fourth chakra, counting from the crown or from the root. It is the middle chakra.
Observing and analyzing this system we can see that a stable way for spiritual development is to move from the root towards the upper chakra. This means that initially, life is about mastering survival after which comes pleasure, then achievements. Having acheived some level of success, a person then starts to understand, and accept, becoming tolerant, this is the heart chakra. Having developed the heart chakra, energy is transmuted, whether consciously or subconsciously for use by the upper chakras. In developing the throat chakra, a person starts to speaks out, expressing views in eloquent ways. With the third eye chakra a person becomes contemplative, naturally reflecting on the lesson of life and gaining insights, possibly delving into philosophy. It is possible that some people jump stages. It is even possible that some people start from the crown. Any which way they want to live their life is fine. Just that starting from root to the crown is quite stable in all stages.
The uderlying concept, as above so below, is valid here. There is an inner development. Yet whereas hop-daddy is with a 'steady' 4, yours is probably a more 'exciting' ride. There are 3 ways to approach this, enjoy it, change it or 'speak'. Any choice is fine, exciting is enjoyable if you can handle it
