Here is another word for your vaisnava vocabulary; Acaryopasanam.
In Bhagavad-gita, Thirteenth Chapter, it is clearly stated that one should execute devotional service and advance on the path of spiritual knowledge by accepting the acarya. Ācāryopāsanam: one should worship an acarya, a spiritual master who knows things as they are. The spiritual master must be in the disciplic succession from Krsna. (from purport SB 3.29.17)
We can understand from Srila Prabhupada, that there are huge gaps in the disciplic succession, but we need to follow the prominent Acarya.
“So these gaps do not hamper from understanding the parampara system. We have to pick up the Prominent Acarya, and follow from him.” (letter to Dayananda April12,1968)
