By way of explanation: Our Sages (Kiddushin 30b) teach that “every day a person’s [Evil] Inclination rises powerfully against him and desires to slay him, as it is written,1 ‘The wicked watches out for the righteous, and seeks to slay him.’ Were it not for the Holy One, blessed be He, Who helps him, a man would not be able [to contend] with it, as it is written,2 ‘G‑d does not abandon him to his hand.’”
There is a verse [alluding to the kelipah] that says,3 “The leech has two daughters [who cry], ‘Give, give!’” In this spirit, the Evil Inclination naturally has a greedy disposition4 which desires and craves whatever physical and material benefits it sees. Its spirit is haughty, [causing a person] to be precious in his own eyes, to exalt himself over others, and to pursue honor and glorification. He does not begrudge others what they own. Not only does he consider his own possessions as being intended for himself alone, but in addition he is envious and craves the possessions of others. All day and all night he pursues the desires and fancies of his heart like an animal. His intellectual activity is directed only toward fulfilling his desires and contriving to satisfy the cravings of his heart.
