We are inside of a screen on which our qualities are depicted. And if they are egoistic, then accordingly they are depicted before our desire to enjoy on the still, vegetative, animate, and human levels (in sizes 0, 1, 2, 3, and 4). Thus, we see them as the world around us. That means the reality I see, feel, and in which I live is an imprint or reflection of the desires and thoughts that are inside of me.
If in addition to my general nature, the qualities of reception, I also acquire a second nature, the quality of bestowal, then just like on a computer screen I reveal one more window on which I see the upper world—the force of my soul. Now I recognize that what I see in the first window is a projection of my receiving forces, while in the second window, I depict the form of my unification with other people for the sake of bestowal.
To the degree I am able to unite with others at least on the level of “don’t do to others what you hate,” to that extent I can recognize the spiritual world. And now everything depends on the calculation I make, on how I continuously awaken myself to transfer reality from the material world to the spiritual world.
The most perfect spiritual state is Purim, which comes from the word Pur—lot. In this state my desires are corrected and I am united with all of the souls, thus fulfilling my soul with the upper Light according to the law of equivalence of form.
Purim is the celebration of the final correction. When we celebrate this holiday, we attract the force from that corrected state which corrects and unites us.
The custom to wear masks and dress up in costumes on this day came to us because Haman (the egoistic desire) dresses into the clothing of Mordechai (the altruistic desire), which means that we can receive Light into the great desires of Haman through the qualities of Mordechai.
This is also why on the holiday of Purim there is a custom to eat cookies in the shape of a triangle called “Haman’s pockets.” A pocket symbolizes the desire to receive. We have to receive these desires from Haman and then, with the help of Mordechai, by means of the Light of Hassadim, the quality of bestowal, correct them by the intention for the sake of bestowal. Then we will be able to receive the Light of Hochma, the revelation of the Creator, meaning the state of the final correction.
