If the friends become more important to you than yourself and your first concern is that they will discover spirituality and not you, it shows the greatness that you attribute to the Creator since by that you want to bring Him contentment. For Him, to reveal Himself is pleasure. He can be revealed only in desires that resemble Him, which means desires of bestowal that are compatible with His bestowal. A person who bestows reaches adhesion with the Creator according to the law of equivalence of form.
But the vessels of bestowal can’t exist in a person himself. They can only be if you take extraneous desires and the more alien they are to you, the better. Rabbi Shimon’s disciples felt such hatred towards one another before they began to study. Imagine what great desires they corrected by raising them in bestowal to the Creator so that He could fulfill His bestowal with them.
It’s the same with you when by wanting to reach the love of the Creator you try to love others, the friends. You agree to take all of their desires and raise them to the Creator for correction. This means that you are ready to be their servant, the conductor between them and the Creator. You only use the Masach (screen) and so you become like mother, Bina, who has nothing.
This is called a “kingdom of priests” that have no estate of their own. The Creator is their only property. You only conduct His Light through you for others and by that reach adhesion with Him.
