Because the created being is opposite in its nature from the Creator but has to reach equivalence of form with Him, we as created beings have these two opposite forms inside us. Our inner form, our desire to receive, is opposite from the Creator and the external form of the desire has to be similar to that of the Creator. This collision, this conflict, breaks us; we cannot get along with it unless we begin our true spiritual work.
Here we develop as every spiritual vessel. First there is only a desire to receive, and then it is restricted. After the restriction a Masach (screen) and the Returning Light appear, and then there is the receiving of the Light and the fulfillment. This fulfillment is not in the vessel itself in the desire to receive, but it is received in the form of bestowal, which the created being has corrected by himself in resembling the Creator.
These two opposite parts are constantly in the created being who has achieved an equivalence of form with the Creator. On the one hand, it is opposite the Creator according to its natural desire, but on the other hand, the form of the corrected desire is in equivalence of form with the Creator.
So sorrow and joy, emptiness and wholeness coexist, and it’s this oppositeness that makes our work whole, since by that we can detach from our “self,” which means from the desire to receive, to rise above it and to speak from the desire to bestowal, from the height we have attained and built above us. This is why there is a Mitzvah (commandment) to work for the Creator with joy, since this is the general formula. We will always feel the oppositeness and the emptiness in our desires to receive, and we should be happy that we have a chance to work above this feeling.
Even if I have no energy to pray and have nothing to pray for or don’t know what to ask for, it’s also a sign that I am on the right track, since I feel a bitter taste in my desire to receive. Here the two opposites meet: On the one hand, I have no energy to pray, I cannot turn to the Creator, there is nothing I can ask from Him and I have nothing to give Him, but on the other hand, I am very attracted to it and I know that I have to attain it.
This area already with two forces, two lines, two opposite directions, indicate that my desire is in a correct process of correction. This alone is a good enough reason to be happy! The main thing is the awareness that I have managed to rise a bit above my desire to receive, towards bestowal.
