Behar: Chapter 14
The secret of the servant and the secret of the son

We learn that one should be in the grade of the servant in order to perform the many kinds of works required; one would then be called, like Malchut, 'master of the whole earth.' The grade of the son is where one strives to know his Father's secrets and all the mysteries of his house, and he then has power over everything; no one can ever stop him from entering his Father's presence at any time. In order to be both a servant and a son, one must undertake the service of prayer - such a one restores the entire secret of the Faith.
