Reiki and Yoga both focus on the movement of energy throughout the body and finding balance for the mind, body, and soul. In reiki that movement is aided by the Reiki master that becomes the vessel for the spirit guided movement of energy throughout the body. In yoga the movement of energy is taught by the yogi through poses, breathing techniques, and meditation. Experiencing reiki work allows the recipient to have energy work done to clear any obstructions in flow.
Karma is powerful law of nature and no one can interfere to stop or change the results it brings about. However, with the right understanding of this essential Buddhist doctrine, we realize that we are the architects of our own fate. We decide our misery and happiness. This gives us the opportunity to correct our negative karma and to have a better future.
