Spirit tells me that what is or seems to be, may be an illusion, and

What might have been or what might yet be is not now.

What purpose then is there to my believing anything if all that

Seems so may be no more than an illusion?  What path to follow if

All paths fade into nothingness?

Choose wisely.

How could any choice be a wise one in such a scenario?

Intuition and intent.

But, my intuition and intent are possibly unique, to me.

Yes, and so is your path.
