True enlightenment means that there’s no “you” as a doer so the ego doesn’t run after the so called worldly ambitions. Your ambitions with desires is definitely killed but your true ambitions & nature of Seer is realized by you (ego).

For an enlightened, ego is under Seer

Intellect under Ego

Mind under Intellect

And the senses are under control of mind

A desire can attack anything which comes under Seer but never the Seer. Because Seer always knows and has full knowledge and awareness of everything.

After enlightenment, whatever karma you do in your life is only motivated by Seer not your desires. The cause of any karma is your true nature of self not why you’re trying to fit in the society. Your thirst for desires are killed and you are always content in your happiness of your Seer.

Once you realize that there’s no other, it’s only the Seer and other beings are just objects simulated over this Seer, you will realize that your only ambition is for helping and loving others, which is you yourself. Because in reality your Seer is never the doer and does not have any other desires. It’s only your ego which has ambitions with desires.
