Answer: If a person is concerned about bestowal to others, he doesn’t have to be concerned about his necessities because they will always come to fill his desires to a sufficient degree. But there are unique situations where a person must take a look at himself to clarify what is essential and where its fulfillment is found. And he sees that this degree of the necessities is found in the desires of bestowal that are directed towards the Creator.
On the level of Bina, a person doesn’t ask for necessities because that is taken care of by itself. He doesn’t have to be concerned about it. This is because the level of Bina is absolute bestowal, Hafetz Hesed, a state of Katnut (smallness) from the side of the vessels, the states of “embryo” and “nursing.”
But when a person goes through greater and higher states and begins to work with the receiving vessels, then he must become active and turn with a unique prayer for the necessities to determine what his work will be for the purpose of bestowal. This is even though he doesn’t have any need for this himself. But he determines that he is a creature, exists, and must exist in order to work to bestow and to serve the people, and therefore he asks for what is essential for himself.
This means that praying for the essentials is an effort for him. He would prefer not to do this, but he must do it as part of his work. This is like the Cohen (High Priest) who had to have special clothing, even though he didn’t need this himself. But in order to serve the people, he had to have special ceremonial priestly garments tailored for him.
This means that the request for the essentials also requires an effort from the person and is not felt as necessary. But this is a part of his work, and he asks for this through overcoming his reluctance.
