The main cleanliness is to be clean from sin, which dirties and soils the soul, and causes damage and dirt in the palace of the King of the world. Even the most minute sin has an effect on his soul and on the upper regions and the Throne of Glory. It also causes other evils which our poor minds are too limited to understand. Because of this, a man should tremble from fear and be extremely careful to keep his hands free from any hint of prohibition, and if he sinned he should hurry to repent and atone for the sins that he has committed, and he should do everything that he is able to clean that which he damaged up there, as if he does not take care to clean and purify himself, the second sin is worse than the first, as he is not worried about the honor of his Creator.
