(1) The explanation is that just as corporeal beings are separated from one another by spatial distance, so too spiritual beings are separated from one another by their difference of form. You can find comparable cases in this world as well. For example, two people who are similar to one another in their perspectives love each other, and physical distance does not cause them to grow apart. By contrast, when they are far apart from one another in their perspectives, they hate each other and physical proximity will not bring them one iota closer. The difference in the form of two people’s perspectives distances them from one another, while the similarity of form in their perspectives draws them closer to each other. If, for example, the nature of one of them is the opposite, in all aspects, from the nature of the other, they will be as far apart from each other as east is from west.
(2) In the same way, you can understand this concept in the realm of spirituality. All the dynamics of distancing and drawing close, or fusion and unification, that are applied to it, are just measures of changes of form. They are separated from one another commensurate with the extent of the difference of form, and they are attached to one another commensurate with the equating of form.
(3) With this in mind, you will understand that although the will to receive is an indispensable quality in a created being, since the will to receive defines an entity as a created being and is the appropriate vessel for receiving the purpose of the Creator’s intent in the creation of the world, nevertheless this quality separates the created being completely from the Emanator. This is because there is a change of form that leads to opposing states between the created being and the Emanator. The Emanator is entirely about giving and lacks even a trace of receiving, God forbid. By contrast, the created being is entirely about receiving and lacks even a trace of giving. There is no difference of form more opposite and distant than this, and therefore this difference of form necessarily separates the created being from the Emanator.
