The best way of knowing something is through direct experience. You watch a beautiful sunrise and you feel joy. There is nothing here that deludes the senses. Another way is through inference. Observing that there is a distortion caused by some invisible object in space, astronomers infer that there is a black hole nearby. Though this is not direct perception, this seems like a perfectly rational way.
There is another way of knowing which is experiential. For example, yogis perceive certain truths by going beyond the mind. They profoundly alter their consciousness and experience heightened levels of insights. They experience knowledge beyond the senses and we consider them sacred. Raja Yoga has detailed descriptions of these experiences. The biographies of Sri M (See Apprenticed to a Himalayan Master) or Paramahamsa Yogananda contain experiences which would be considered blasphemy in dogmatic traditions.
This also gives an opportunity for charlatans to claim the same experience. Since it is the experience of one person, how can one validate it? Usually, when two of our perceptions do not contradict, that is proof enough, but here are talking about experiences beyond ordinary perceptions.
Rather than depending on a central authority, these systems are self-validating. There are few simple rules which can help to figure out if the person is making up things or if this is really a sacred experience. These are simple rules which long living civilizations can hold in their memory.
They are
- It should not contradict past knowledge in that tradition
- It must be true knowledge by someone who has transcended the senses.
- It depends on the character of the man
- This experience must be verifiable.
- He should not be selling this knowledge
In science, if a mass murderer like Stalin, makes a discovery, it is acceptable. That is not acceptable in dharmic traditions. The person has to be sattvic, following a well-established path (See No one does yoga anymore)
If someone says, this is an experience that only I can have and that the rest of us have to trust that, it has to be rejected. In scientific traditions, anyone should be able to have those experiences, provided they follow the right path.
Once we understand this, it is easy to figure out why there is so much hatred towards a decentralized, self-validating and self-sustaining tradition which has sustained for millennia. The fact that anyone can be divine goes against the only-one-divine-person-and-trust-him dogma. Belief in this dogma causes them to destroy anyone who does not believe so. (All in the name of “religious freedom”). Once you become a dogmatic prisoner of science too, you shut yourself from these possibilities by restricting yourself to what is directly perceived and inferred. Our mind and body are capable of much more.
