All that we experience is subjective.
There is no sensation without interpretation.
We create the world and ourselves;
Only when we stop do we see the truth.
The world exists, but we cannot truly be one with it in our normal modes of consciousness. Our minds know the world by constructing conclusions from the data of our senses. All that we know is filtered and interpreted.
Therefore, there is no such thing as objectivity or direct knowledge of the world. Everything is relative because we are each condemned to our particular vantage points. As long as we all have different perspectives, as long as perception relies on our senses, then there cannot be an absolute truth. All knowledge from experience, valuable as it may be, is imperfect and merely provisional.
Inner truth is only glimpsed by disconnecting the mechanism of interpretation. If we can withdraw the activities of the senses and isolate that part of the mind responsible for filtering sensory input, then we can temporarily shut off the ongoing process of interaction with the outside world. We will then be in a neutral place that is wholly turned inward. We are left with an absolute state, entirely without distinction or relativity. This is called nothingness, and it is the truth underlying all things.
