That, after all, is how the scientist as well as the spiritual aspirant determines what obtains. Did you know that he asks sincere students to NOT speak of him to those without interest or who are busy in other labs. Rarely does one find Direct Personal Experience detailed online. Identity comes from one's own direct experience. That is the means to gain wisdom.

The image shown above symbolizes the universality of righteousness as a lotus, the petals of which are the religions of Man. The Sarvadharma is a circle of faith, each petal equal and yet distinct, the center of which is illumination. This symbol is meant to say without words that the radiance of divine truth, pictured in the center, is at the core of all religions, and manifests as the illumination of spiritual wisdom in each culture and milieu as time and place require. That gives rise to an intellect free of distractions, and it is that focused and unforced steady attention which reveals the truth about Reality. I suggest then that it is primarily through self-enquiry that one finds what is lasting among what is temporary.
