So what is the difference between the words “Veda” and “Vedanta?”
The word ‘Vedanta’ means the end (or final chapters), or essence of the Vedas, the ancient sacred scriptures of Hinduism. The end portions of the Vedas are also called the Upanishads.
Ok, so what are the Upanishads? These are not the same as the Bhagavagita, that’s an allegory of a family fued in heaven, similar to the tales of the Olympians.
The Upanishads are the stories of searches of the flesh and blood holy men, the yogis of the past.
Through spiritual practice we can discover our true Self, which is pure Spirit, distinct from the body and mind, perfect, free, and one with Divinity itself.
Now the Upanishads have nothing common with the Book of the Law, but in a sense, given how early it is in the Aeon, its actually our responsibility to come up with our own New Aeon, Thelemic Upanishads, based on our own records of our work.
