Siddhartha's awakening from the illusion of permanence gives us reason to refer to him as the Buddha, the Awakened One. Now, 2,500 years later, we see that what he discovered and taught is a priceless treasure that has inspired millions.
from What Makes You Not a Buddhist
by Dzongsar Khyentse Rinpoche
The community at Siddhartha's Intent are people who have been inspired by what Siddhartha discovered, by what has been taught in an unbroken lineage from Siddhartha all the way to present day teachers like Dzongsar Khyentse Rinpoche.
We are a relatively small community. Most people know each other. So we use our real name for example--we want to create an environment of openness and genuineness, in which we can further explore the teachings of the Buddha.
