There is a line from the Hermetic writings that has stayed with me for weeks.
In the thirteenth treatise of the Corpus Hermeticum, the young disciple Tat asks his father, Hermes Trismegistus, to teach him the secret of spiritual rebirth. Hermes does not hand him a doctrine. He gives him a condition:
“When you are ready to become a stranger to the world I will give it to you.”
The answer is unsettling because it is not information. Hermes is not saying “study harder” or “learn more.” He is saying that until something in Tat changes, the teaching cannot be received, however clearly it is explained.
I came across this passage in Gregory Shaw’s essay Taking the Shape of the Gods: A Theurgic Reading of Hermetic Rebirth. The more I sat with it, the more I heard it echoed in nearly every mystical tradition I know.
A Tradition That Outlived Empires
Hermeticism is a strange and beautiful survivor. Its texts were written in Greek in Roman Egypt, probably in the first centuries of the Common Era, but they present themselves as the wisdom of Hermes Trismegistus, the “Thrice-Great” Hermes identified with the Egyptian god Thoth.
The fourth-century Neoplatonist Iamblichus, one of the most important figures in late antique philosophy, took these writings very seriously. As Shaw explains, Iamblichus believed the Greeks had lost touch with a sacred way of knowing, one that had been preserved by the Egyptians in the writings of Hermes. For him, the Hermetic texts were not curiosities. They were a living path to the divine.
At the centre of that path is the idea of rebirth: becoming, in some real sense, a new being. Hermes tells Tat plainly that “this thing cannot be taught.” It can only be entered. The doorway into it is estrangement.
What struck me most was how universal this teaching is. Across cultures and centuries, the mystics keep returning to the same figure: the stranger, the traveler, the passer-by.
In the longest psalm of the Hebrew Bible, David prays:
“I am a stranger in the earth: hide not thy commandments from me.” (Psalm 119:19)
The two halves of that verse belong together. Because the speaker is a stranger in the world, he asks for what is hidden to be revealed. Estrangement is not a complaint here. It is the qualification for receiving.
The Gospel of Thomas
In the Gospel of Thomas, found among the Nag Hammadi codices (the same Egyptian library that preserved Hermetic texts), Jesus gives what may be the shortest spiritual instruction ever recorded:
“Become passers-by.” (Saying 42)
In another saying he is sharper still: “If you do not fast as regards the world, you will not find the kingdom” (Saying 27).
The Prophet Muhammad ﷺ
In Islam, the Companion ʿAbdullah ibn ʿUmar reported that the Prophet took hold of his shoulder and said:
“Be in this world as if you were a stranger or a traveler.” (Sahih al-Bukhari 6416)
It is one of the most beloved hadiths in the Sufi tradition. The traveler stops at an inn, rests and is grateful, but he never confuses the inn with home.
The Upanishads
In the Mundaka Upanishad, the seeker must first examine all the worlds that can be won through worldly action and “acquire freedom from all desires.” Only then does he take fuel in his hand and approach a teacher, who reveals to him the knowledge of Brahman (Mundaka Upanishad 1.2.12–13). The order is the same as with Hermes and Tat: first detachment, then transmission.
The Tao Te Ching
And from ancient China:
“In the pursuit of learning, every day something is acquired. In the pursuit of Tao, every day something is dropped.” (Tao Te Ching, ch. 48)
This is the Hermetic insight in reverse. The way is not found by accumulating. It is found by letting go.
In all of these sayings, the stranger or traveler stands for detachment: from the world, from its desires, and from the endless grasping of the ego.
The heart, in the language of so many traditions, is meant to be a vessel. If it is already full of attachments, cravings and anxieties about what we have and what we lack, there is no room for anything else to enter. As long as the heart is crowded, one cannot, in the words of the Neoplatonists, take the shape of the gods.
This is the root of asceticism on the spiritual path. Across traditions, seekers have fasted, kept vigils, withdrawn into solitude and given up comfort and luxury. They did this not because the body is evil, but to loosen the grip of the senses and desires. Iamblichus called this stage catharsis, purification.
Shaw describes its purpose beautifully. Catharsis exists to “overcome the confusions of embodiment and allow the divine to take its seat in one’s own body” (Shaw, 2015, p. 158).
That last phrase, in one’s own body, is where the story takes a surprising turn.
Read quickly, all of this sounds like a call to escape. Leave the world, deny the body, rise above matter. Many scholars have read Hermeticism exactly that way. Garth Fowden, in his influential study The Egyptian Hermes, interpreted Hermetic rebirth as an escape from the body and the physical cosmos.
Shaw disagrees, and this is where his essay becomes truly illuminating.
Following Iamblichus, Shaw argues that becoming a stranger to the world belongs only to the Lesser Mysteries, the stage of cleansing. To stop there is to mistake the means for the end. The Greater Mysteries lead somewhere unexpected: not away from the world, but back into it, transformed.
In the culmination of this path, the purified soul receives the divine energeiai, the creative activities of God that flow through all things. The body itself becomes what Iamblichus called “an organ of the gods” (Shaw, 2015, p. 163).
Hermes himself hints at this. In another treatise he tells Tat that matter, bodies and essence are all activities of God, and he concludes: “There is nothing that he is not.”
So the stranger does not finally abandon the world. The stranger learns to see it again, no longer as a prison, but as the living activity of the divine.
Shaw sums up the whole Hermetic path in a single paradox: rebirth “is realized as giving birth, not escaping from the world but creating it.” The initiate takes on the shape of the gods, yet remains mortal, “holding our natural place in the cosmos.”
I think this distinction matters a great deal for anyone on a spiritual path today.
There is a kind of spirituality that stops at detachment. It becomes a quiet contempt for the body, for ordinary life and for the material world. It can look like holiness, but it is still a kind of duality: spirit good, matter bad, heaven up there and the world down here.
The deeper teaching, found in Iamblichus, in the Sufi idea of returning to the world after annihilation in God, and in many other traditions, is non-dual. Detachment is the doorway, not the house. We let go of the world so that we can receive it again, rightly.
The traveler in the hadith does not hate the road. He simply does not mistake it for home. And because he is not trying to possess the road, he is free to notice its beauty.
In my own journey, I have experienced that letting go of attachment and desire brings a quality of unshakeable peace and bliss. It is real, and it is unmistakable when it comes.
To become a stranger to the world is not to leave it, but to stop being possessed by it, so that the world can be received again, this time as the body of the divine.
Perhaps that is as it should be. Hermes did not promise Tat that rebirth would come quickly. He only said: when you are ready.
What has detachment meant on your own path? Have you found it a doorway, or have you found yourself stopping at the threshold? I’d love to hear your reflections in the comments.
