You are transfiguring. This means that your transformation happens not only on an energetic level but also on a physical level. This can result in headaches and fatigue. It is your DNA which is changing because of new insights and your cells are being ‘informed’ accordingly.
Organs react to this too; old patterns and negative beliefs are changed into waste, which the body rids itself of. These can be intense experiences, but please realise that we are on the way to a new consciousness, a new knowledge and creation. Even if you feel far from being enlightened, please understand that everything is going according to plan, and your body just needs time to deal with the energetic changes.
The frequency of Transfiguration helps you to find rest during these periods of change, so that the physical side effects will fade away into the background.
