Momentaneous in a sentence as an adjective

Other Buddhist texts say that the world annihilates itself and reappears six thousand five hundred million times a day and that all men are an illusion, vertiginously produced by a series of momentaneous and solitary men. The being of a past moment of thought — the Road to Purity tells us — has lived, but does not live nor will it live.
