One of the true characteristics of all worldly phenomena, together with indivisibleness, identicalness, specific conditionality, change and transformation, emptiness, equality and illusion, which the Buddha recognized in his enlightenment.  All worldly phenomena have suchness.  Suchness envelops the whole universe, it cannot be divided, it is immovable, immutable and beyond expression, it is not born.  Things as large as the sun or as small as a speck of dust all have suchness.  When applied to human beings, it is also called Buddha Nature (P & S: Buddhatā, V: Phật Tánh).
