One of the true characteristics of all worldly phenomena, together with suchness, indivisibleness, identicalness, specific conditionality, change and transformation, emptiness and equality, which the Buddha recognized in his enlightenment.  All worldly phenomena appear to be real but in reality, they are ever-changing and their true nature is emptiness.  Therefore, the appearance of worldly phenomena is illusionary and ephemeral, like a dream, a shadow, a flash of thunder, a magician’s trick.
