Ramakrishna
said, "Only two kinds of people can attain to self-knowledge: those
whose minds are not encumbered at all with learning - that is to say,
not overcrowded with thoughts borrowed from others - and those who,
after studying all the scriptures and sciences, have come to realize
that they know nothing."
That last part is when the jnana yoga path is really working, because the "know nothing" is the next step in this trip. You learn and you learn and you learn until you realize that with all you've learned, you don't know anything - and that's the route through. You use your intellectual models to get you going - they're really helpful for that - but you don't cling to the models; you keep letting go of them, letting go of the intellectual structures. Otherwise they get in your way.
