All mystical traditions are one.
They are the seed of all religions.
Tao. Zen. Tantra. Yoga. Kabbalah. Sufi. Mystic Christianity. Shamanism. And so many more secretly treasured by their adherents. These all share the same mystical sense of communion with the divine. Meditation is not something peculiar to one culture.
All cultures know a mystical core that emphasizes continuing refinement, meditation, and unification with the greater cosmos. I call that greater order Tao. They call it by different names. What does it matter what people call it? When they discovered what was holy, they uttered different sounds according to their history and culture, but they all discovered the same thing. There is only one divine source in life.
For generations, mystics of all traditions have plunged into Tao. When they meet on the unutterable levels, they know without words that they have reached the same core of spirituality. No matter where in the world you are, there are traditions with the purity to lead you to Tao.
