Answer: This action symbolizes the cleansing of a person’s egoistic hands with which he tries to grab everything for himself. By washing them, he as if corrects his egoistic intentions and does not use them anymore. This is called “washing one’s hands.”
Question: That is, if I perform this action in spirituality, it corrects me. What about corporeality?
Answer: In the corporeal world, it is a reminder to a person that he must abandon the egoistic use of his desires.
Question: If a person washes hands with this intention, does this give anything to him?
Answer: Nothing! People should not get confused. As it is written: “You shall not make for yourself a graven image” in absolutely everything.
You can do whatever you want: eat, drink, behave as you please, as long as this is good for people, and then you will come closer to the upper world. The only condition is the rule “Love your neighbor as yourself.”
