The truth will not set you free

Why are lies, deceit and deception so prevalent?

Because they are helping us to get what we want. And they are useful tools if we need to get off the hook.

So, why do we despise these excellent tools?

Because we have to pretend that we don't use them, otherwise they wouldn't work.

We have evolved to survive. To be honest and playing fair will only cause problems for you.

The English variant "And You Shall Know the Truth and the Truth Shall Make You Free" is carved in stone in the Original Headquarters Building of the Central Intelligence Agency.

Warning to Rich Oppressors

Now listen, you rich people, weep and wail because of the misery that is coming on you. Your wealth has rotted, and moths have eaten your clothes. Your gold and silver are corroded. Their corrosion will testify against you and eat your flesh like fire. You have hoarded wealth in the last days. Look! The wages you failed to pay the workers who mowed your fields are crying out against you. The cries of the harvesters have reached the ears of the Lord Almighty. You have lived on earth in luxury and self-indulgence. You have fattened yourselves in the day of slaughter. You have condemned and murdered the innocent one, who was not opposing you.   (James 5)

Selfish Personality Disorder

Selfishness is also on a spectrum, like narcissism. Severe forms of selfishness ought to be included in the DSM-6. It could be called Selfish Personality Disorder, SPD.

All narcissists are selfish but all selfish assholes are not narcissistic.

Selfish people hide their selfishness behind an agreeable mask. They are also hiding their selfishness for themselves. They don't even know that they are selfish. Some of them even believe that they have always been too nice and kind.

They lie both to themselves and to others, they slander, talk bullshit, and believe that they are completely innocent. Feelings of anxiety, guilt, and shame will be the result. They don't understand why they have these feelings so they stuff themselves with antidepressants, anti-anxiety medications, and junk food. They try to hypnotize themselves with "positive thinking and self-affirmations". They are completely stuck in the mud of lies and self-deception.

Lost in translation

Genuine mystical experiences should not be transferred into written words, not even into spoken language - unless you are talking to a very close friend. You should not throw pearls before swine.
