Yes, a foundation is needed. TEOREI is an intensive Advanced training, so first take a Foundations training – Reiki All-in-One (Module 1), Level 1 of one of the flames or Green Tara Seichim Level 1. This way the material is understood and absorbed better. At Level 1 “The Path of Conscious Creation” you receive the attunement to the TEOREI energy and learn the Four Pillars of Creation, the inner temple, sacred symbols and hands-on and distance energy work. If you already practise energy work, you will find a new, complete framework for your work.
