The image below is a very simple representation of the stream of thought which flows eternally. The most current point of the stream is in constant motion perpetually moving forward. As the stream flows, pools are left behind.
Imagine that when you are in perplexion, consideration, contemplation, active deep thought, you are moving through the body of the stream of thought itself. However, once you come to a conclusion, forming a judgment, assertion, or belief, then your thought energy enters and rests in a pool.
The idea is to be as nearest to the current as possible.
There are three stages of sorcery: (disassociate any meaning you may have with the colors I used in the image and the image itself beyond what I describe please)
Blue Phase - This is when the mage learns to use items to awaken energies that connect them to spiritual worlds.
Purple Phase - This is when the mage learns to use items to shift into the spiritual world through the astral senses.
Red Phase - This is when items are no longer required for any magickal work and the mage realized there are no separations from the spiritual world but those limitations which exist in his own form.
I myself spent four years which apparently is not that much time but these days I am Red Phase. Granted I spent many years before that having encounters I was wholly ignorant of. It wasn’t until much later I gained a conscious handle on things which I was experiencing.
The stream of thought flows and is eternally flowing and has eternally flown even before life. Any being which thinks accesses and begins flowing within the stream itself, It’s not until we enter the conclusion pool that our energies settle. It is nice to rest in some conclusions or remember certain old one’s from your memory like from childhood but the idea is to attempt to access the most current part of the stream itself.
Keep in mind it is both impossible and absurd to think you could reach a point in front of the stream. For the current of thought is on the threshold of nothingness and creates energies and dimensions as it flows. The ideal is to back in the most current flowing point. To attempt to reach this attainment is called the ‘path of the Forerunner’.
