Quotes:Oak, sacred
H. P. Blavatsky
Sacred Oak. With the Druids the oak was a most holy tree, and so also with the ancient Greeks, if we can believe Pherecydes and his cosmogony, who tells us of the sacred oak “in whose luxuriant branches a serpent (i.e., wisdom) dwelleth, and cannot be dislodged”. Every nation had its own sacred trees, pre‐eminently the Hindus.
