It is the intensity of the faith one has in the F.S guidance that is most important; once that is there, the grace flows automatically. The faith in the F.S guidance is based on the Ataman [consciousness] which is the true self. F.S is directing the seeker to higher level of understanding.
The means of releasing the nondual truth is through rectifying the seeking base, which is part of the process. Understand the false as false, that's all seeker of truth, has to do; he cannot accept anything as truth without verifying them through inquiry and reasoning.
People are viewing and judging the truth on the base of the physical level, they are not going back to their state before the waking experience came into existence. Before waking experience came into existence, there was only Ataman. Therefore prior to this waking experience, one must recede into that, which is formless.
When seeker finds and realizes the Ataman as true self and eternal identity, he has no need struggle to drop the duality which he is experiencing it ads reality it will automatically becomes unreal, therefore he has to strive to get the firm conviction that Ataman is the true self, and all else is falsehood other then Ataman.
The F.S guidance touches the serious seekers very deeply. And seeker abides with the firm conviction that Ataman is the true self No more doubts and confusion exists on the base of Ataman as self. If seeker never bothers about other teachings and he hangs on to the messages of F.S it becomes better and faster for him to assimilate the self knowledge.
Seeker has to know exactly what this waking experience is, how transient it is, and he also has to know what that eternal state is. Seeker of truth has no use for this ephemeral experience of duality in pursuit of truth. When one becomes aware of the Ataman as true self then what meaning he attaches to the waking experience.
