Matthew 12:34 – 37

O generation of vipers, how can ye, being evil (with Cain, the Ego very alive), speak good things (utter the Truth)? For out of the abundance of (virtues in) the heart (through the Holy Denying) the mouth speaks.

A good man
 (the one who knows himself through meditation) out of the good treasure of the heart (which is his Internal God) brings forth good things: and an evil man (the one who feeds Cain and his Seven Demons) out of the evil treasure (which is his Buddhata trapped within his Ego) brings forth evil things.

But I say unto you, that every idle word that men shall speak, they shall give account thereof 
(before the Lords of Karma) in the Day of Judgment.

For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
