Hi Mike!
In the Pure Energy course the energies are very compatible with each other. When you do the meditations one after another (without the 20-30 minute break)the free flow of moving energies has a cumulative effect and you will be amazed at the inredible breadth and depth of your experience.
With many other modalities, the energy is moving in a certain specific direction. Butting two different techniques up to each other can disrupt the flow and interrupt the integration of the new frequencies.
I think you'll be pleasantly surprised when you run Deirdre's meditations together in the same session. Enjoy!
All the best to you!
Wendy
