"Living Guru" not always present (ISKCON) ys pd

Chandra wrote: "Srila Prabhupada Letter to Dayananda, April 12, 1968: "Regarding parampara system: there is nothing to wonder for big gaps. Just like we belong to the Brahma Sampradaya, so we accept it from Krishna to Brahma, Brahma to Narada, Narada to Vyasadeva, Vyasadeva to Madhva, and between Vyasadeva and Madhva there is a big gap. But it is sometimes said that Vyasadeva is still living, and Madhva was fortunate enough to meet him directly. In a similar way, we find in the Bhagavad-gita that the Gita was taught to the sungod, some millions of years ago, but Krishna has mentioned only three names in this parampara system--namely, Vivasvan, Manu, and Iksvaku; and so these gaps do not hamper from understanding the parampara system. We have to pick up the prominent acaryas, and follow from him. There are many branches also from the parampara system, and it is not possible to record all the branches and sub-branches in the disciplic succession. We have to pick up from the authority of the acharya in whatever sampradaya we belong to.""
