Manbyō no Reiyaku – Miraculous remedy for all diseases. This is how Mikao Usui Osensei referred to his hands-on healing method in Usui Reiki Hikkei, a handbook he wrote in 1923. And this is how we refer to the course material compiled by Master Dae Chong, specifically for the purpose of self-healing, based on his 20 years of experience in healing and teaching. (His lineage is: Usui M. – Taketomi K. – Koyama K.- Doi Hiroshi – Chong D.). The training became available to the general public in 2018. It contains everything that is necessary for self-healing and later, with practice, for the treatment of family members and friends.
