Some thoughts out of the experience of mystical reality:
The human spirit is just about being human. But the human soul is something else. It is part of a Reality that is bigger than any name humans or their religions can give it, including names like God, Holy ghost, Shabd, Baraka or Consciousness, for instance. This Reality has been experienced by some humans throughout history. The phenomena is now being seriously accepted and studied by scholars, academicians and scientists around the world.
The human spirit is just about human culture, morality and ethics. But the experience of Reality is that there are bigger things afoot than mere humanity. Are humans and what they call the human spirit as important in the scheme of existence as humans think they are?
