You are mistaken, a personal experience is not invalidated because it is not some physical substance, if others can replicate the experience, then it becomes a part of the common knowledge of the culture. That some people have not or do not want a particular experience is not evidence that the experience is not real. The Dharmic traditions of India that have spread earlier through most of Asia and later throughout the whole world has allowed hundreds of thousands of devotees, if not millions, to realize the bliss associated with a still mind over the millennia.
What you cannot seem to fathom is that evidence required verification from other EVIDENCES, in order it to be fact.
Personal experiences are highly unreliable. And just because you have followers of the same religion, believing in meditation and transcendence, doesn't mean much because they are bound to be biased, since they followed the same religion as you.
If outsiders, like me, cannot independently have the same experience as you, then it is all based on your believe in your own religion.
If you remember my cattle farm example, you can have 5 inspectors, each one with different belief.
For example, you can have a Jew, Christian, Muslim, Hindu, Buddhist and an atheist. And each one will independently count exactly 100 cows, regardless of their religious belief or lack of one.
With science, any person employed as a researcher or lab tech, have to do his work, without involving his theism and atheism, or whatever -ism he or she may personally follow.
Any testing or experiments done, will have to done from scratch, without considering previous test result of previous experiments, or hope that future experiments will confirm your premise or hypothesis.
In murder investigation, homicide detectives will interact with possible witnesses, and explore the motive of a killer. Forensic specialists don't interview witnesses or suspects, they don't profile for possible motive, because it is not their jobs. Forensic lab techs would process the evidences, not psychoanalyse anyone or find out who's telling the truth and who's telling lies. So a murder investigation explore the incident from two different fronts, one is more objective than the others.
It doesn't matters if the suspects or witnesses are telling truth or not, because each testimony is very subjective.
And you are not being objective on the matter, since you already have invested interest in your religion.
