You ask:
"Can I turn inward AND also act in the world at the same time?"
There are so many ways to avoid separation from the world, life, meaning and just being, so many ways to simpleness, that, which is here, that, which you have forgotten, that, which you must remember.
Your brain has shot a lot into oblivion and has magnified something out of proportion. It organizes everything in linear sequences and thus creates time.
You have already learned, that there is only moment upon moment upon moment... that's all you can say, because words seem inadequate, yes, like describing love.
Yes, with words you can come close, but love can only be fully experienced, felt ... like the sentient fetus in the womb; it cannot describe what surrounds it, but it can experience, feel, it knows. Remember this:
You experience yourself, and this you do not have to leave.
You feel yourself, and therefore you cannot be thrown anywhere.
