And even if he might know that his soul is from "Malchut of Asiyah" or whether it is from "Yesod of Asiyah," etc, each of these [people] must fix/rectify all of the entire world of Asiyah [meaning, the whole Torah, Mitzvos, and Halachos are from the world of Asiyah. We need to master these first!]. Then, he can receive his Ruach which is from Yetzirah which is higher than the entire Asiyah. Also, even if he is able to reach his Neshama which is from Beriah, a person must fix all of the parts of his Ruach [first] within all of Yetzirah.
Then, he will be able to receive his Neshama which is from Beriah, and it is not enough for him to fix only the specific place which is the source ("shoresh") of his Neshama. [In summary, a person has to first fix all of the parts of his Nefesh which is in the world of Asiyah] until he "graduates" from the entire world of Asiyah, and then he will receive the Ruach (which has its source in the world) of Yetzirah, etc. throughout all the other worlds.
Here is the explanation: A person should toil in Torah and Mitzvot in their completion, and he shouldn't stop learning or fulfilling them regardless of where he is in the source of his Nefesh. He should learn Torah and do the Mitzvot (which have their source in the world of Asiyah).
