Thank you for your great question!
Desires are sort of like dreams which give us the opportunity to suffer when these desires do not get accomplished or suffer as well once, we accomplish something, for we will find out that “it is not as we thought it should be,” and we will keep on “desiring” for something else. Desires are like a cancer which keeps reproducing itself with no end. No peace. As you mentioned, once we attach ourselves to the result, because we want it in a certain way; we set ourselves for suffering.
You mentioned that “everything starts with a desire.” Apparently that seems the case, when there is ego ruling our lives. Even the desire to be “self realized,” will produce suffering if that does not happen. Self realization is not a desire but a realization of being. Something that “happens.” You are, and because you are, you are experiencing yourself. There is an internal motivation to “move” in that direction which is not a mental “desire,” a thought about something; but that “inner motivation” is without thought, it is a driving force which will take us there for those who have it in our roles, in our fortune.
That is why, there is no need to “desire” this.
Once we know that there is a “Drama” and that we are eternal beings and that a law of “cause and effect,” exist; then rather than having a “desire” we could be driven with a realization based on knowledge, not in just a “wish,” which is a desire.
For those who do not have that realization at the core of the being, for it is numberwise; then different levels of desires will exist.
I cannot deny someone who has the desire to get a promotion at work and works “hard” for it. His consciousness is giving that person that desire. Once he fulfills that desire, he will learn something new.
In spirituality we cannot “deny” things to people, we can merely give some suggestions. If someone does not have the realization about desires yet, I could hurt him if i tell him “You must not have that desire to get a promotion,” for his consciousness is not ready yet. That “repression” will create further issues.
Through this Godly knowledge we have teachings which are geared for Brahmin souls to be “number 1,” that is “not to have desires,” however; reality is that we are numberwise.
BapDada’s method is always to aim for the highest but at the same time to simplify spiritual teachings for the masses, by using the main virtue of love. That is why when He mentions” You should not have desires,” he will add “The Father will satisfy all your desires if you are obedient. So have no desires.” That is a teaching based on our level of trust with the teacher.
This teaching then could be interpreted as a way of suppression, when applied as a blanket for every single BK, without using the knowledge of “numberwise.”
In the realization of the being, that is self realization, we could encounter that which we are looking for. Once we have found it, there is no need to desire for anything else. That is, “the Father has fulfilled all your desires.”
