The Book of Zohar, “VaYikahel,” Item 141: Therefore, it is forbidden to kindle a man’s voice during prayer, so that the upper voice, ZA, will be in it, since the speech rises to Malchut and unites with ZA through the Malchut, receiving a voice that is mitigated from ZA. Then the prayer is fit for reception of the abundance, and the speech of the upper world need not be heard through a man’s voice.
There is a rule, “there is no vessel without the Light.” Everything is done by the Light only, while we only exert ourselves, which is the precondition for every action. Every single action is done only by the Light that works on the vessel.
We are only required to exert ourselves; we don’t do anything but only increase the intensity of the deficiency. This is the reason we are in our world, since this is the only place where we can perform different experiments and actions, which from a spiritual perspective are not considered actions. They only bring us to a state in which we can ask for the correction of the vessels and for their filling.
This is why our world is so special. If we didn’t exist in this reality we wouldn’t be able to influence our spiritual ascent in any way, since all the actions are performed only by the Light. So how can I, being on a certain spiritual level, influence something that is higher than that level? By which means can I do this? I have to be detached from the spiritual world in order to ask to be raised from one state to another, from one level of clarification and new correction to another.
There has to be a reality that is detached from the spiritual ladder, which is where I am, in which I can always prepare for the prayer before a prayer. This is the reason that the corporeal actions in our world are so beneficial to reach a certain state and to ask for the Light that Reforms. We shouldn’t think that we don’t need our world, that we can do nothing but simply connect internally and that this would be enough.
This isn’t enough. On the contrary, the more a person does in practice, the more desire, pressure, and experience he builds up inside him as a result of all his actions, which eventually add up to a cry, to a prayer before a prayer. The prayer before a prayer is addressed to the Light with a request to form the vessel, the desire. The prayer itself is addressed to the Light so that it will fill the vessels, which means that it will actually allow us to bestow.
