If you read piously somebody’s teaching, then that person might be your psychagogue. By that, I mean guiding you through psychological teaching.
Carl Jung wrote about his discussion with an old Indian man, about gurus.
Jung asked him if he knew about his guru, whereby the elderly man replied in the affirmative. (Jung, p. 220)
He was Shankaracharya, the commentator on the Vedas, who died many hundreds of years ago. The Indian man explained it was Shankaracharya’s spirit who guided him.
Carl Jung wrote in his autobiography that he thought Philemon was his spiritual guide. If you do research online, you’ll read that Philemon was a Christian who lived during the period of Paul the Apostle. Paul wrote Philemon a letter, asking him to forgive his slave Onesimus, who escaped from captivity. Paul asked Philemon to forgive Onesimus and see him as his brother in Christ, and not view him as his slave property. This story is in the Bible, in the New Testament, as Epistle to Philemon.
