Dualism is essential to human functioning; because even self-described monists are actually dualists, with their duality being reality versus illusion.
However, the monist type of dualism is paralysing, because there is no guide for thinking or acting - any potential thought or action is equally valid (or illusory); all is equally beautiful (or vile), all is equally virtuous (or wicked), all is true (or false).
The tendency is towards inert contemplation and yearning - mortal, incarnated life on earth is seen as intrincially illusory, and therefore ultimately meaningless, purposeless, a waste of time ('time' also being illusory).
So we need to take care in picking our dualism! These fundamental assumptions have implication for the everyday. Indeed, one primary aspect is whether our dualism is a static or dynamic dualism - whether we assume that reality is developing or just-is, whether time is real or just an appearance?
Assuming we have chosen a 'dynamic dualism': What then should I do - here and now?
I need to become aware of the flow of creation - feel its direction and get into harmony with that direction, by aligning my own will with that of The Creator. This may happen only through loving The Creator - it is love that harmonises my wishes with the potential direction of on-going creation.
I need to know (to experience) where creation (that bit of it relevant) has come-from and is going-to. I also need to know my-self and how my thinking, scting, creating can be included in that on-going creating. So I need both love and intuitive knowing.
Intuition is being-aware-of ongoing creating; and its meaning and implications for me - here, now.
The key insight is that there is creation, and that creation is not everything; there is also that which is outwith creation - we could call it chaos.
Creation is made-from chaos - through time; in an on-going process.
The intended direction of creation is towards greater consciousness on the part of beings such as you and me; greater awareness both of creation and of our own place in it: awareness of on-going creating and our own sub-creating within it.
This mortal life is therefore intended for increased consciousness - or else, if unawareness were equally desirable, there would be no need for bodily incarnation (we could instead be spirits); there would be no need for agency (since we could behave automatically, determined as a dependent part of creation); there would be no change/ decay/ disease/ death (because we would just exist in static harmony with creation).
Or, if consciousness did not matter; we need not exist at all; since our existence would then add nothing substantive to creation).
So, with an imperative of greater consciousness; there is always something for each of us to do: At any time or place or situation, we each need to be more aware of on-going creation and our own part in it.
