This ascension through successive lives from one grade to another was the idea behind Chaturvarnya, the fourfold soul types, soul involved in Matter (Shudra), soul involved in the circulation of vital forces and energies (Vaishya), soul involved in vital ambition, power, strength (Kshatriya) and soul involved in mind and pursuit of true knowledge (Brahmin). Later this deep knowledge was lost and the system became something based on mechanical inheritance, hence the Time Spirit has broken its outer form. But the inner truth exists for anyone to see.
Affectionately,
