Answer: It’s because otherwise you won’t be able to achieve bestowal and exit your nature! You must demand the reward above your nature, beyond it, and build yourself in bestowal for the sake of bestowal (Hafetz Hesed), without demanding any compensation for your ego.
It is necessary to be in selfless bestowal, in pure Bina, above all the actions, even if within those actions and the matter in which you execute them, you still expect a reward. Indeed, it is completely impossible to carry out certain actions and not expect any reward for them, remaining above the egoistic calculation.
And this is why, due to the environment and by utilizing all the conditions, we reach a state when we demand of the Creator to give us this ability: to not demand the reward for ourselves. I don’t know how He will do it or what it is; I have no idea how I will execute these actions of bestowal, but I want to!
We are always developing this request within: from degree zero to the final, fourth one, at every phase, with every examination. This is how we advance until we reach the true demand which finally reveals this quality within us.
