All that makes up this world is relative. All knowledge depends on beliefs, words and concepts.
What happens if the beliefs are dropped for a moment? What happens if the concepts are seen as relative? What happens if the words are seen only as signposts and not the actual thing, not the actuality? What happens if the conduit for all these things, thoughts, is paused?
What is the only thing you are certain of? What is the ONLY thing you don't need words, concepts or beliefs to know, to be absolutely sure of?
Isn't it the fact that you ARE? Can you deny that you are? Is this a concept? Do you need words to describe it? ARE there any words to describe it?
We say "I am a man", "I am a woman", "I am happy", "I am sad". This I AM is certain, the rest is relative - man, woman, happy, sad...
So we stay in I AM only - stop right there. Drop off the rest. This I AM is obvious, but it is still a thought, a pointer back to what is your true essence.
You don't need the thought or words to know that you ARE - drop off the word and thought "I AM" also - rest in the actuality of I-AM-NESS, which IS, prior to any words or thoughts.
Isn't this I-AM-NESS a simple knowingness? A primary principle which is always there to witness the coming and going of the world, the coming and going of the relative?
This I-AM-NESS isn't relative, it doesn't depend on anything, doesn't change, is untouchable, unshakable... it doesn't have moods, doesn't have a bad day, doesn't have feelings to hurt, isn't affected by suffering, never moves, never is added to or taken away from.
This I-AM-NESS is like a little spark - it stays put while the world seemingly rushes by. Even the appearance of the passing of time happens while the I AM stays put, PRIOR TO time. The world may appear to cover up this little I AM spark, however upon close investigation the spark is the light illuminating the world, the very principle upon which the world depends.
You know this I AM - it's inescapable, unavoidable... it doesn't need to be learned or gained or attained, isn't the product of meditation or blissful spiritual experiences. But you add all the labels to it and then identify with them and miss the already-present I-AM-NESS, the silent/still ACTUALITY which is presently seeing and knowing the sound and motion, the relative, witnessing the illusionary world created in imagination.
Realize that this world and this person are relative, based entirely on knowledge gained within the dream itself. Stories are happening, suffering and bliss take their turns. All the while, the real you, the true Self, is looking in unaffected.
