Which energy therapy is derived from ancient Buddhist rituals?

Reiki therapy is indeed derived from ancient traditions and has its roots in Buddhist rituals. It originated in Japan in the early 20th century and is based on the concept of universal life force energy, which practitioners believe can be harnessed to promote healing and balance in the body. The practice of Reiki incorporates principles of mindfulness and meditation that are inherent in Buddhism, aligning with its philosophy of interconnectedness and the healing aspects of energy.

In contrast, the other options represent different systems and practices. Yoga therapy is primarily focused on physical postures, breath control, and meditation, although it has a spiritual component related to Hinduism. Crystal healing involves the use of stones and crystals to promote healing, which is not specifically tied to Buddhist practices. Quantum healing, while it incorporates some aspects of energy work and consciousness, does not specifically derive from Buddhist rituals but rather from contemporary interpretations of quantum physics in relation to healing.
