Reiki brings about the self healing required for self realization. 

Raja Yoga takes one through the royal path of self realization. 

Therefore, both are important. Self healing is a prerequisite for self realization. 

How can a heart craving for the world, crave for God? And still stay in balance? First balanced abundance has to be achieved, then comes non-attachment to that abundance, and then comes single pointed devotion to God.
