The Torah, “Numbers,” 17:1 – 17:2: And the LORD spoke unto Moses, saying: “Speak unto Eleazar the son of Aaron the priest, that he take up the fire-pans out of the burning, and scatter thou the fire yonder; for they are become holy; …
Although the Torah speaks about desires, every spiritual action is expressed in our world in the form of corporeal objects. Therefore the depiction of the fire-pans they used to offer incense in the Temple were kept until our very days.
This means that people used to work that way with their desires, from which the Returning Light rose, meaning that they pleased the Creator and brought Him pleasure.
When a person works with the intention of in order to bestow, he resembles the Creator and thus becomes closer to Him and can adhere to Him. He ascends from Malchut to Bina and then from Bina to Keter; this is what the rising incense symbolizes.
