iddhipāda (pali; skt. "ddhipāda") is a compound term composed of "power" or "potency" ("iddhi"; "ddhi") and "base," "basis" or "constituent" ("pāda"). in buddhism, the "power" referred to by this compound term is a group of spiritual powers. thus, this compound term is usually translated along the lines of "base of power" or "base of spiritual power." in the buddhist pursuit of enlightenment, the associated spiritual powers are secondary to the four "base" mental qualities that achieve such powers. these four base mental qualities are: concentration on intention; concentration on effort; concentration on consciousness; and, concentration on investigation. these four base mental qualities are used to develop wholesome mental states and rid oneself of unwholesome mental states.
