Let's say you are overweight, and have always been more or less overweight, and I tell you if you exercise, lose some weight and eat healthy, you will feel more energetic and have a clearer mind... You can either have faith in me, take my word for it and give it a shot, or ignore what I say because you've never experienced such things, or don't believe it is possible to be any more energetic and have a clearer mind.
So, the "ultimate truth" is like that too. It does exist, but you getting there might require you to try new things which might also require you to put your thinking process on hold for a while until you see the results of the new things you are doing. In the mean time, don't harm anyone.
