Reiki · definition
The teacher-to-student chain through which a Reiki practitioner traces their training tradition.
How the term is used
Lineage is often used to identify the school, teachers, and style through which Reiki instruction was transmitted.
Why it matters
It helps readers understand why Reiki systems and terminology can differ.
Where this fits in a practice
The guides explain the idea in context; the service pathways are there when reading is not enough. Educational content only — nothing here is medical or mental-health care.
