How did the world come into being from Brahman, according to the teachings in this chapter?

Chapter 50 outlines a specific cosmological sequence for how the world emerged. It begins with Brahman, which became 'qualified' (shabal) by Avidya (ignorance) and was thus given the name 'Sat' (Existence), making it expressible and graspable by the intellect. From this expressible Brahman, the 'Unmanifest' (Avyakta) emerged. Following this, the 'Great Principle' (Mahat-tattva) came forth, and within it, egoism was born. The process continued with the five Tanmatras (subtle elements) forming within the ego, and from them, the five great elements arose. Finally, Chapter 50 explains that the world itself was born from the womb of these five great elements, concluding that the visible world is simply the form of Avidya-Maya.
