Nature is not comfortable with straight lines. Like the back of a cobra's head. There is something magical and menacing about the triangle and the square. The city block. The book. The cell phone you are holding. The number. The river is never the same place twice. The number is constant. The city block remains the same until the hurricane washes it back into the sea.
So there are "seven" stages of evolution. This I have heard. And am uncomfortable with. Both the number and the concept of evolution. And the person selling the books touting both. I imagine my ancestors. Am I more evolved than them? Am I even more evolved than me as a fetus? Assuming achieving unity is the sin quo non of spiritual pursuits are all these practices, earnestly striven for nothing more than the circular return to where we started? And thus, as we live and age, are we not becoming more fragmented?
Perhaps the most vivid "mystical" experiences are nothing more than a recapitulation of youthful memories and experiences?
Sure, you can develop your ego, build your spiritual resume in a million different ways that people do. Give a million lectures, write a million books celebrating spiritual evolution. But i imagine my friend with down's syndrome who cannot write a coherent sentence "emptying" himelf and touching upon higher dimensional spaces than the most accomplished mystic.
There is no high expression of humanity, no low expression. What we do, we do for the whole. What we touch, we touch for the whole. Where some parts of the unified organism expression may temporarily come into contact with the light, they will blend back into the mass for the next wave to come into the sunlight.
But who knows? Who has given up the knowledge? Who has manifested the sacred geometry of straight lines into their consciousness and become something else? Who has cleared the portal for something different to emerge into this space?
