Devarim 15:9

Verse 9. Beware lest you cherish the thought arising from the evil unregenerate heart, saying, it is most certain that in a holy celestial state everything good is perceived to come from the Lord; and your understanding regard as evil the humble strivings after good in the soul, and you in no way endeavour to satisfy them; and thus the good impulses from the Lord be rejected within you, and thus you open your soul to evil.
