It takes a tremendous amount of courage to turn away from the habits of our culture, in addition to turning away from our own habits so that we might eventually see our true nature. Such a turning away involves turning away from long established biases, presuppositions, memories, trust in sensory consciousness and a host of other things. One cannot begin to approach gnosis of one's true nature carrying such things around.
Yes, intellectually we can all agree. Still, this intellectual view, true as it is, is burdened by old habits—many not-so-good ones which are still with us—and huge. Our spiritual wings cannot as yet lift the bad habits we've acquired, beginning in our childhood, and continuing to the present. The burden is too great. And it is here that our courage is called for. We have to have the courage to dump all of this. Our intellect is too weak to do anything, even though we know its judgment is correct. Somehow we have to stop making excuses and start dumping all the heavy habitual garbage.
But I can imagine someone now asking, "But how do we get the courage?" For that I don't have the perfect answer. I just know that it takes a lot of little courageous acts which I hasten to add, is much different than rebellion. Remember, this is about the courage to clean out our dump: the old biases, presuppositions, memories, etc. This stuff for us has to be light enough to let go of. We have to be able to say goodbye to it all sufficient to enable the pure subject to see the pure object thus overcoming the crippling mode of consciousness.
Making things worse is a lack of faith. In other words, we are not quite persuaded that such a true nature or Buddha Mind is for real; only needing to be uncovered by right practice. Incidentally, this is what pisses me off about modern culture. I see it as highly destructive of a spiritual view of man. We live under a materialistic regime that I dare say is evil to the bone. If seeing our true nature requires lots of faith in addition to courage we won't find help in this present day materialistic regime. The good news is that within the next hundred years the Newtonian world view will be over and with it the collapse of mechanistic science as we know it. In the meantime, we have to renounce the modern world by seeing through its deceptions; most notably the fact that its ontology is materialistic: all phenomena is ultimately constituted of matter rather than mind (G., Geist).
