Let us compare the Process of Transformation with that of the metamorphosis of a caterpillar to a butterfly.
Once the caterpillar weaves its cocoon, imaginal disks begin to appear. The blue print of the butterfly to come is carried in those disks.
Although the disks are a natural part of the caterpillars evolution its immune system actually recognises them as foreign and tries to destroy them.
As the disks arrive faster and begin to link up the caterpillars immune system breaks down and its body begins to disintegrate.
When the disks mature and become imaginal cells they form themselves into a new pattern and transform the caterpillar into a butterfly.
This is similar to the Process of Transformation within the Human Being.
For the new you to emerge the old you will need to first disintegrate. The experience is of disks clumping and new parts of you forming only to fall away again until the next clump comes, until finally you transform into your true nature.
