Rudolf's Steiner lectures here describe the Origin of the Cosmos as a Rosicrucian Cosmology. He also uses the Esoteric language of Hindu and Buddhist sages.
These lectures are unique in that the translator (Rick Mansell) did not convert the phrases from the Sanskrit so they are deeper and richer in meaning. Our database of words gives you access to another world of concepts and interrelationships of meanings. You can spend days just researching our database.
