Question: There are also sufferings and troubles other than pleasures, what names should we give them?
Answer: We name things according to the vessels, to the desires. It’s because we understand and perceive everything in the vessel, including the Light. It doesn’t exist by itself, apart from us, but rather like electricity about which we speak only with regard to its effects. Similarly, we discern the phenomena that stem from the Light, the effect of its actions inside us.
Pleasures are extra Light, a filling by the Light, and everything is revealed in the vessel. This is where the names stem from. Each one indicates the beginning and end of an action, as well as what happened in the actual process.
The name expresses an action that was performed by the force behind it. We, the created beings, have no other way to describe something. It’s because we don’t have any contact with the Light itself. We are limited in the matter of the desire and the form it takes on as it changes from its initial state until it resembles the Creator.
