The reason relative truth seems like Truth to some people is that all the brain will every experience is what it can perceive, which is information having to do with this physical plane. In other words… Actual Truth exists in a vibrational plane that is too subtle for the brain to perceive… [what can experience Truth is one’s Intuition].
So, if you are yourself Enlightened to some “degree,” then to that exact degree, you will “hear” and “see” that level of truth. And if you are really Enlightened, then you will “see” and “hear” [capital “T” Truth]. But those capable of this are rare.
And if you know someone who tends to speak Truth, then by all means try and spend time with that person.
