Most people have desires, and when their desires are unrealized, they feel bad.
However, they usually go towards only one form to deal with this problem, and that is the first form in Taoism, the weakest form.
Form 1 - Weakest form - trying to make reality serve your desires
Most people try their best to make reality match their desires. They chase and make endless effort every day, just so that reality finally says "yes" to them.
Alter reality to match desires = reality matches desire
However, this is entirely futile form. Reality says "yes" to no one. It is actually you who must say "yes" to reality. It is like standing in front of a rock and wishing it becomes chocolate. The wish is never granted, and wisher never happy.
When you can actually alter reality to match your desires, this form is useful. But at all other times, it is useless. Thus, it is not a complete form and not always useful, thus weakest form.
Form 2 - Mirror of reality
This is probably one of most effective forms. Instead of trying to change reality, just accept it. Instead of wishing for a rock to turn into chocolate, wish it to stay a rock and your wish is granted.
Alter desires so they match reality = desires match reality
Instead of trying to alter reality to match desires, alter desires to match reality.
Form 3 - Mindless monk
Probably my second favorite form. Instead of trying to make some equation between your desires and your reality, just abandon desires completely. This way, you don't need to try and change your desires so that they match reality. Abandon desires completely, so there is no unachieved desire. So there is nothing happening which you want gone, there is nothing which isn't there which you want it to be there.
No desires = no desires unrealized
Form 4 - Delusional monk form
This is my favorite and probably strongest form.
Unlike the previous 3 forms, this form alters neither reality nor desires.
Instead, it builds delusion that desires are already realized even if reality says they aren't.
So this is actually about altering perception of reality, not reality itself.
Delusional monk in his imagination has already achieved all his desires, and he confused his imagination for reality. That's why he won.
Confusing imagination for reality = desires realized in imagination are confused as realized in reality.
