Reality is the interval between two thoughts.
Are you aware of the significance of every thought, of every reaction that you happen to have?
Self-knowledge is not a thing to be bought in books, but it is awareness, from moment to moment.
Do you become spiritual by performing ceremonies and rituals…? Ceremonies and rituals sometimes give a certain sensation, so-called uplift. But they are repetitious, and every sensation that is repeated soon wearies of itself.
