Q. What about the holy bloodline of the rose, the grail knights and how is that still relevant in our time?
A. The holy bloodline was a interesting theory. The problem with it was the priory of sion (who were teaching it) were proven to be a hoax and there is no real evidence for it. The knights templar were guardians of a gnostic school from what i have read. The grail was a legend made up by monks in the 12th century though it was probably infleuenced by pre christian legends. From how i see, there is no need for purification or some kind of spiritual quest to some far away place when the god nature is all around us. Non duality is a little scientific as was early christian gnostic mysticism. There is a tbeory that the gospel of thomas was the real grail. An attempt to keep the wisdom of the gnostics alive.
