It is possible to utilize for G-d’s service, according to Torah, all behavior-traits. This includes those traits that are unwholesome, and even those that are evil, as their names and descriptions indicate. For example, the tzadik Rabbi Meshulam Zusya of Anipoli, of blessed memory, learned a number of methods of serving G-d – from a thief:
b) He is ready to place himself in danger.
c) The smallest detail is of great importance to him.
d) He labors with great toil.
f) He is confident and optimistic.
g) If he did not succeed the first time, he tries again and again.
