As David R. Hawkins points out, the fundamental limitation of the human mind is that it's unable to tell the difference between truth and falsehood, positives from negatives, and that which is beneficial from the harmful. Thus, we have problems in our lives and in the world.
If we all actually knew the truth, and were living that truth, there wouldn't be a single man-made problem in the entire world, ever, because truth doesn't ever create problems. Only falsehood creates problems, or the illusion of "problems."
David Hawkins' book Power vs. Force provides a solution to the human brain's built-in ignorance; a means to tap into pure all-knowing consciousness so that we can drop negatives from our life, adopt positives, and solve the world's problems. We can now tell - instantly - whether anything at all is true or false, despite all opinions about it.
Power vs. Force is a monumental achievement in the study of consciousness that will undoubtedly, if practiced, change the world in profoundly beneficial ways. The painful process of learning by trial and error can now be a thing of the past, and consequently, the evolution of mankind has the potential to make huge leaps and bounds in very little time.
If you're a fan of "The Power of Now" and other such "self-help" style books, or anything on the topics of enlightenment and the nature of the ego, Power vs. Force will change your world in ways you can't even imagine. I HIGHLY recommend this book (and Hawkins' others). It's absolutely vital reading for anybody on the spiritual, philosophical, or even scientific path. If you seek truth of any sort, at any level, this is the ticket.
To give a (very) small taste of what you'll find, here's a few quotes from the book:
"Intelligence and rationality rise to the forefront when the emotionalism of the lower levels is transcended."
"By taking responsibility for the consequences of his own perceptions, the observer can transcend the role of victim to an understanding that 'nothing out there has power over you.'"
"Relatively few people are genuinely committed to peace as a realistic goal, for in their private lives, most people prefer being 'right' at whatever cost to their relationships or themselves."
"At the lower levels of consciousness, propositions are accepted as true even when they're illogical, unfounded, and express tenets neither intellectually provable nor practically demonstrable."
"Facts are accumulated with great effort, but truth reveals itself effortlessly."
"Man's dilemma - now and always - has been that he misidentifies his own intellectual artifacts as reality. But these artificial suppositions are merely the products of an arbitrary point of perception."
"There is only one absolute truth; all the rest are semi-facts spawned from the artifacts of limited perception and positionality."
