As a rule, we gather all our actions, thoughts, and feelings together and aim them at the Creator. But here it says that He directs all His streams of water to us, to Malchut.
Malchut is the spiritual place where all souls who want to come into contact with Him gather. This is a place of meeting with the Creator. Both we and the streams of water from the Creator rush there.
The upper waters are the upper light, the light of Hassadim (the light of mercy).
In fact, all the commandments that are repeated in two ways, referring to the act of creation, first speak of a movement from below-up, from the souls to the place of meeting with the Creator, and then from the Creator to the same place of meeting with the souls, explaining how we should come to our common place of meeting.
