if you are still seeking once getting to a certain point of consciousness then you are still in the process of obtaining further truths suggesting your previous comprehension of truth may not necessarily be correct at any point in time
so tbombz quote still stands
The point is, you should always continue to consider that there may be alternative courses with anything. Alternative courses of action, alternative ways in which things may work, alternative ways of doing things, etc... if you view the world as if everything is at least possible, you will learn far, far more than accepting "truth" then closing your mind off from all other possiblities.
(Again, I agree with his statement for the most part, BUT, I also believe in progress and the fact that a definate REALITY is what makes progress possible.)
