The Razor's Edge

I am reading a book by Osho called The Pillars of Consciousness, which contains a collection of four of his earlier works on Buddha, Zen, Tao and Tantra. In the section on Tantra, Osho refers to the Middle Path as "the razor's edge". I have heard this term in two slightly different contexts-one as the title of a Somerset Maugham book, while the other as a song by the band Rush. Well, maybe I will articulate a bit on what this term now means to me.
   The razor's edge is exactly what it describes--a painful, knifelike, precarious condition. It's somewhere in between striving and being, where striving is stymied by being and being is pulled asunder by striving. The razor's edge is being caught in the knowing that one is a negation, yet not having any way to fill that negation. Then resting in the negation and the absence of a negation. This razor's edge is also an eternal guilt--we are never fully ever finished, yet we might sometimes feel like we are "cooked" (even overcooked), and there is always one more mountain to climb. So there is an anguish there.
   None of these explanations of mine particularly relate to Buddhist notions of the middle path, but I think it suffices to say that nobody in good faith can rest in some eternal certainty. Perhaps, paradoxically, they can realize that nothing is ever clear and focused or finished. A life lived in guilt of things committed in the past is really only the seed for some future redemption or something that needs to be paid later. A person cannot wallow in guilt, the way a creature might hide in mud to escape from predators-nor can one wear guilt like it's a kind of "forever me". These ways of cloaking oneself in the past are evasions of the fundamental voidness that guilt points to. When I do something wrong, nothing exonerates me--that wrong remains fixed in my mind, no matter whether I run away from it or rationalize it. Nothing can write over the anguish of past wrongs, which makes it infinite. On the other hand, guilt can be redeemed, just as we can constantly renew our vows to do good things. Guilt can spur a person to greatness, much more so than a life that is completely "innocent" (a theoretical life, no doubt). This is because seeing harm or wrong is the greatest inspiration to seeing what is good. Good is sometimes only known and felt in the not-good. Alas, this is the terrible thing about the good. By the time one has recognized it, the opportunity to be innocent has passed.
    Razor's edge is an awakened state, sometimes raw and painful. It is eternally never-resting.
