The Sanskrit word Parampara (literally, uninterrupted series of succession) refers to the process of succession inside an established Sampradaya, sect or tradition. The succession of parampara is a strict succession. There is never more than one active master at the same time in the same guruparamaparya (lineage).
In most Guru Sampradayas, the selection of a successor is based on an appraisal of the disciples by the Guru. The selection of the most qualified disciple is made as an act of Will to ensure the continuity and proper continuation of the line. The process of Paramapara or succession is finalized upon the death of the former Sampradaya Guru.
