What's the process described for how the world was created from Brahman?

Chapter 50 outlines a specific process of creation starting from Brahman. It explains that Brahman first became qualified by Avidya (ignorance), which allowed it to be expressed as 'Sat' (Existence) and take form through the 'Omkar'. From this expressible Brahman, the 'Unmanifest' (Avyakta) emerged. From the Unmanifest came the Great Principle (Mahat-tattva), which gave birth to egoism. Within egoism, the five Tanmatras (subtle elements) arose, and from them came the five great elements. Finally, as the chapter states, from the womb of these five great elements, the world was born. The text concludes that the world itself is a vision or form of this Avidya-Maya.
