In her latest and very personal book of mystical essays about Professor Severus Snape, Logospilgrim shares how he has influenced her spiritual journey and practice. She writes about Oneness, balance, transcending duality, compassion, letting go of certainty, and universal unconditional love. She writes that Professor Snape is like the Whomping Willow. . . He is the staircase "that led somewhere different on a Friday." He is the Department of Mysteries.
