2. Veasisa Bigdei Kodesh Leahron:^[1]

A. The priestly garments of the soul in the higher and lower Garden of Eden:

Aaron the high priests is considered one of the seven shepherds of the Jewish people and his job description is to imbue the Jewish soul with love of G-d. The priestly garments of Aaron are the garments for this love. The practical correspondence of the priestly garments for the souls of Israel are the fulfillment of Mitzvah’s with concentration and intent. Every single soul has two sets of garments that are created from the fulfillment of Torah and Mitzvah’s, one being created from the concentration and emotions that were felt during its fulfillment and one being created from the action of fulfillment itself. These garments which are created from the concentration and love serve as the clothing of the soul in the higher Garden of Eden. The garments that are created from the actual fulfillment of the Mitzvah, irrelevant of the intent and emotion, create the clothing which are worn by the soul in the lower garden of Eden.

B. The length of man’s life corresponds to the number of garments he needs to make:

The verse mentions the making of the priestly garments for Aaron and his sons. Mystically, this corresponds to the soul of every single Jew, as every single Jew needs to make garments for himself in this world so he can enter the next world clothed and be capable of receiving pleasure from the Divine presence, as explained above in length. Now, G-d allocates an amount of days in a person’s life corresponding to the amount of garments that his soul needs up in heaven. A soul that requires more garments will need to live more days so he can fulfill more Mitzvah’s on each day. A soul who needs less garments will have shorter days.
