Thank you for your comments.
Knowledge is experiential. To go by literal interpretation of words is the most elementary way of trying to understand spiritual knowledge. Then, we are stuck with a Guru’s interpretation who can tell us what is the “right way” to view things.
We understand once we live this knowledge. Words are merely pointers, that is why we have different scriptures and different views because our experiences are different. By making a particular version the “right” version, we are not using our ability to discern. Once we understand a point in gyan we can share it, and we can provide support for it based on Gyan as well. That is how we could advance into a different understanding.
Many times, interpretations are meant to fit a particular “dogma,” or religious philosophy. Obviously with his kind of agenda, interpretations will be made to fit that “ism.”
Our spiritual edification is based on experience of spiritual knowledge, then there is no need for “proof,” because you become the practical proof of it.
