And you can crash 6 generation's worth of good DNA with a few drugs in a few years ; gene expression changes in enzymes eventually cause DNA-RNA transfer degeneration. For example if you have a child after having been high on meth for years, even if you don't consume for the time of the pregnancy, your child will have dopamine related attention problems; its a very complex matter.
You are both right in a way, but I see it more deep than that, the DNA is the coiled snake brain ; the spring, the golden mean spiral.
We have a reptile brain, a kind of birdish brain, and a neocortex.
This is also reflected in the way old cultures refer to how non human souls make everything that you see alive.
Tell a native shaman that a table is dead he will laugh at you and think you are crazy. He would tell you that it is filled with serpant souls.
Serpant souls not only hold things together in a linear way, our meridians of energy also look like snakes in our body.
Angelic or "maria" souls are known to be those who modify DNA...
Dragon souls are what steers the wormhole of our manifestation.
This is all very old knowledge, the serpant is the worm, the spice is the worm, the worm is the spice.
Follow the snake, to the lake, the ancient lake, it's loooong, 7 miles.
The snake eats his tail and is the symbol of self-realised knowledge, it is the donut of 7 colors, 7 musical notes, 7 main chakras.
7 is even a number that is symbolic of the serpant on the cross.
The serpant is the kundhalini or sexual drive, horizontal drive being primitive, and "grasping the serpant" in "straight" cross with the 4 elements etc etc...
It's fun I can finally talk like this... why is is so important ? Because it's one of the first archetypes layers in holographic knowledge ; it's also an arch-angle ; called Lucifer.
You will understand how these archetypes shuffle with some practice, Lucifer is the serpant yet it is the wigned serpant, it's non wigner brother is Yahlweah or Enlil(ea) ; whom is the vengeful god.
Here is a famous flamel drawing that represents the unification of the 4 elements and the sexual energy feeding higher evolutionary goals.
Here is a quite simplistic but concise representation of the serpant as 7.
And here is a very profound picture linking the amanita as the water bearer , the grapes, cannabis and the golden snake as opposition or motivating force to push towards ascension.
Am I going too fast ?
