Hallel During Passover
137. It is written, “Seven days there shall be no leaven found in your homes.” The joy is during all seven. Hence, why do they not say a complete Hallel [praise, consists of selected Psalms] all seven days of the Passover, as is done on Sukkot, when a complete Hallel is said for the joy every day?
138. On Passover, Israel were not completely tied as they were tied later. For this reason, on the first night, when there is the coupling of ZON and everyone is in a state of joy, and Israel are connected in that joy, we create wholeness and the Hallel is complete. But later, through the rest of the days of Passover, although all seven degrees HGT NHYM shine on the seven days of Passover, Israel are still not connected to them and have not made the exposing, to make the holy record appear in them. They have not received the Torah and have not entered the degrees HGT NHYM, which entered later.
For this reason, there is wholeness on Sukkot, but on Passover, they have not been rewarded and there was no wholeness in them yet. Although all seven days are present, meaning HGT NHYM of ZA, on the seven days of Passover, they are not revealed and Israel have not been properly connected to them until after the giving of the Torah.
139. Hence, the joy of all and the complete Hallel is on the first night of Passover because of that part to which Israel was tied. This is because the coupling is at that night, and the whole connection of all the degrees that were revealed is from the side of the coupling, from the awakening from above, and not from Israel. When the coupling of ZA is in Malchut, the two degrees, HB are on her, too. When they are present, the whole Guf [body], the whole of the level of ZA is present with them. And then it is the completeness of everything and the joy of everything, and the Hallel is completed, since then the moon, Malchut, is crowned with everything. But this is not so after the first night, for each of the seven days there are HGT NHYM, but Israel have not yet been rewarded with them. Thus, the Hallel is not complete, as it is on other times.
