The lord said to Cain, “Why are you angry, and why has your countenance fallen? If you do well, will you not be accepted? And if you do not do well, sin is couching at the door; its desire is for you, but you must master it.”
Be sober, be watchful. Your adversary the devil prowls around like a roaring lion, seeking some-one to devour.
1 Peter 5.8
Whoever lives contemplating pleasant things, with senses unrestrained, in food immoderate, indolent, inactive, him verily Mara overthrows, as the wind blows down a weak tree.
Whoever lives contemplating the impurities of the body, with senses restrained, in food moderate, full of faith, full of sustained energy, him Mara overthrows not, as the wind cannot shake a rocky mountain.
Dhammapada 7-8 (Buddhism)
O men, God’s promise is true; so let not the present life delude you, and let not the Deluder delude you concerning God. Surely Satan is an enemy to you; so take him for an enemy. He calls his party only that they may be among the inhabitants of the Fire.
O believers, follow not the steps of Satan; for whoever follows the steps of Satan will assuredly be bid to indecency and dishonor. But for God’s bounty to you and His mercy not one of you would have been pure ever; but God puri-fies whom He will; and God is All-hearing, All-knowing.
Yes, there are two fundamental spirits, twins which are renowned to be in conflict. In thought and in word, in action, they are two: the good and the bad. And between these two, the beneficent have correctly chosen, not the maleficent.
Furthermore, when these two spirits first came together, they created life and death, and now, in the end the worst existence shall be for the deceitful but the best thinking [Heaven] for the truthful person.
Of these two spirits, the deceitful one chose to bring to realization the worst things. But the very virtuous spirit, who is clothed in the hardest stones, chose the truth, and so shall mortals who shall satisfy the Wise Lord continuously with true actions.
Avesta, Yasna 30.3-5 (Zoroastrianism)
When Israel stood before Mount Sinai, the impurity of the serpent was removed from them, so that carnal passion was suppressed among them, and in consequence they were able to attach themselves to the Tree of Life, and their thoughts were turned to higher things and not to lower. Hence they were given heavenly illuminations and knowledge which filled them with joy and gladness. Further, God girded them with cinctures of the letters of the Holy Name, which prevented the serpent from gaining power over them and defiling them as before.
But when they sinned and worshipped the golden calf, they were degraded from their high estate and lost their illumination, they were deprived of the protective girdle of the Holy Name and became exposed to the attacks of the evil serpent as before.
Zohar 1.52b (Judaism)
The Essence of Mind or Suchness is the real
While heretical views and the three poisonous
elements [greed, anger, delusion] are Mara.
Enlightened by right views, we call forth the
Buddha within us.
When our nature is dominated by the three
We are said to be possessed by the devil;
But when right views eliminate from our mind
these poisonous elements
The devil will be transformed into a real
