Prabhuji explains the answer of the Yogendra, Prabhuddha. He also explained how the conditioned soul bound by the three modes of material nature, is unable to work for his ultimate benefit. Therefore, he has to seek the shelter of a bona fide Guru.
tasmad gurum prapadyeta
jijnasuh sreya uttamam
sabde pare ca nisnatam
brahmany upasamasrayam
--Srimad Bhagavatam 11.3.21
["Any person who is seriously desirous of achieving real happiness must seek out a bona fide spiritual master and take shelter of him by initiation. The qualification of a spiritual master is that he must have realized the conclusion of the scriptures by deliberation and arguments and thus be able to convince others of these conclusions. Such great personalities, who have taken complete shelter of the Supreme Godhead, leaving aside all material considerations, are to be understood as bona fide spiritual masters."]
