What is Primordial substance?

Primordial substance refers to the fundamental material or essence from which all things are believed to arise in various philosophical, cosmological, and alchemical traditions. It is often considered the original state of matter or the universal source of creation, embodying properties that predate the differentiation of elements or forms. In some contexts, it can be associated with concepts like the void, chaos, or the first cause in metaphysical discussions. The idea serves as a foundation for understanding the origins of the universe and the nature of existence.
