If you think you are not relying on any mental constructs - beliefs - I say you are not looking hard enough. We need our mental constructs to get dressed in the morning, to walk down the street without falling down.
Jgnat, you didn't say as to who you were referring the above statement, however since I too mentioned "mental constructs", i would like to reply. The mind is a wonderful tool, and we require it's mental constructs on a day to day practical level. However, to unquestionably believe that the mental constructs of some particular religious dogma is factual is to live a fairytale and become blind and numb to what is real, actual, and true. What is watching the mental constructs? Is That, a construct? Can It, be written, spoken, or somehow limited to or placed in a box? How deep does it go? Paradoxically, we believe in beliefs (notice the circle) because we feel a need for something to fill the void where Reality seems missing. Missing, because our attention is on beliefs rather than Reality. The way out of the circle is to stop believing, use the minds thinking abilities only when necessary, and be very present with what the universe is presenting in this present moment (silently, and void of mental commentary and judgment). In other words, really be with Life/Reality. Then see. Go deeper into what is already true, and see what it has to teach and reveal. Really discover what has been here all along; and rediscover that you are not the lost and broken child believed to exist. j
