There are people out there who actually believe that knowledge is a bad thing, and most of those people are religionists. Most believers in religion shun it and think it's "of the devil." No, IGNORANCE is the devil's work. BLIND BELIEF is the devil's work. Tricking you that good is evil and evil is good is the devil's work.
There's no such thing as "evil" or "negative" knowledge. Knowledge is neutral. It's a toolset. What makes it good or bad is how you use it.
Refusing to discover the truth about anything because it challenges your belief system and your egoic attachment to it is exactly what evil wants. It wants you unconscious, docile, ignorant, lazy, cowardly and apathetic. It wants you sitting around doing nothing, believing untrue things, constantly indulging in sensate pleasures, thinking morality is whatever you want it to be, and shirking your personal responsibility for freedom to some phantom savior while it runs amok unchecked and unchallenged.
Religion doesn't want you active and engaged, it wants you in thrall. It doesn't help you to develop spiritually, it suppresses the spirit. It doesn't teach sovereignty or the infinite value of freedom, it teaches powerlessness and servitude. It doesn't teach true objective morality, it gives you a false, arbitrary "morality" based in the whims and preferences of a priest class.
True spirituality isn't a religion or a belief system, it's a way of being in the world. It derives from Knowledge (of the Self and the Universe in which the Self exists and operates). It derives from true Self-Love and Self-Respect. True spirituality is understanding your Sovereignty and Rights, and acknowledging and respecting the Sovereignty and Rights of other sentient beings. It is living in harmony with Cosmic Moral Law, having True Conscience, doing the right thing because it's the right thing. It has zero to do with belief.
True spirituality is about Freedom. Agapé Love (higher consciousness; Love for Truth, Justice, and Freedom for all beings) is the firm foundation by which all peace, prosperity, freedom and order is created. Fear (low consciousness; willful ignorance, blind belief, cowardice and apathy) is the perilous foundation by which all suffering, tyranny, slavery and chaos is created.
Which do you choose? Love or Fear? Freedom or Bondage? Order or Chaos?
