Initiation, Eternity and the Passing Moment is the volume catalogued as GA 138 in the collected works of Rudolf Steiner. It gathers a cycle of seven lectures given in Munich between 25 and 31 August 1912, together with a related eighth address on the meaning of the anthroposophical movement. Steiner delivered the cycle to open that year's Munich festival week, the same gathering that staged reconstructions of the ancient Eleusinian Mystery. The lectures take a single guiding thread: the nature of initiation, the human longing for what is eternal, and the way that longing meets us not in some distant afterlife but in the living quality of each passing moment. This study guide is an original introduction to the volume, written to help a reader approach the lectures with a clear sense of their setting, their argument, and the concepts they open up. It does not reproduce Steiner's text; it maps the ground so that the primary source can be read with more understanding.
Place in Steiner's Work
By the summer of 1912 Steiner had spent more than a decade building a body of spiritual teaching, and GA 138 belongs to the phase in which he was drawing that teaching toward its Christ-centred core. The Munich cycles were traditionally the high point of the anthroposophical year, opening with dramatic art and continuing into concentrated esoteric instruction. This volume sits alongside the great initiation lectures of the period, close in spirit to the work Steiner had done on the Gospels and on the being he called the Christ. It also arrives at a hinge moment in the history of the movement. Within months of these Munich days the wider theosophical body would split, and Steiner would establish the independent Anthroposophical Society. The closing eighth lecture, on the anthroposophical movement as an answer to the spiritual questions of the age, reads in hindsight as a quiet preparation for that parting of ways.
What distinguishes GA 138 among the initiation lectures is its steady insistence that spiritual knowledge is not the property of a remote elite. Steiner traces a single stream flowing out of the ancient mystery centres into the ordinary religious and cultural life of humanity. The various faiths of the world, in his account, can be seen as an out-streaming from the initiates, so that the impulses once guarded in the mystery schools have gradually passed over into the general life of mankind. Initiation, in this reading, is less a private attainment than a service rendered to the whole of human evolution. A reader coming to the volume from Steiner's better-known books will recognise the connection: he several times points the audience toward his written guide to inner development, treating the lectures as a deepening of practices already set out in print rather than a separate doctrine.
Themes and Structure
The cycle opens by placing itself in the setting of the Munich festival and the reconstructed Eleusinian rite, then moves inward. Steiner argues that anyone who would speak truly of higher worlds must first submit ordinary concepts to a certain change, because the ideas we form from sense experience will not carry us into the super-sensible. Much of the middle of the cycle is given to this re-molding of thought: how the seeker learns to hold ideas in a more fluid, living way before those ideas can become instruments of genuine perception.
A second strand runs alongside this training of thought. Steiner describes how the several worlds of existence work reciprocally, so that within any one world the influence of the others can be perceived as a kind of reflection. In each world we meet the beings proper to it, and also everything that streams into it from elsewhere. This picture of overlapping, mutually reflecting worlds is what allows him to speak of the secrets of initiation, the relation of the passing moment to eternity, and the relation of the darkness in life to the light of the spirit as a single connected theme rather than three separate riddles.
From there the lectures turn to the figures of the initiates themselves. Steiner surveys the great teachers who have given light to humanity across the ages and asks what distinguishes one from another. He draws a careful line between the older initiates, who worked through their higher spiritual bodies, and what he presents as the wholly different manner of the Christ event. He is careful to say that comparing whether one initiate stands higher than another is, in his words, empty talk; the point is not ranking but understanding the distinct way each has served human development. Woven through these discussions is the title's paradox: eternity is not an endless stretch of time waiting beyond death, but a quality that can shine through the present instant. The passing moment, rightly met, becomes the doorway to what does not pass. Steiner puts the practical heart of the cycle plainly:
Let us turn our gaze to the initiates who give light to mankind as the ages go by.
The seven lectures build cumulatively rather than treating separate topics, so each returns to the same questions at a greater depth: what initiation is, how the soul prepares for it, and why the search for the eternal is also a search for the meaning hidden in ordinary experience. Because the cycle is progressive, later lectures assume the shift in thinking that earlier ones asked for, and a reader who tries to begin in the middle may find the later material harder to follow than it needs to be. The appended eighth lecture, given the same week, steps back to view the movement itself, describing anthroposophy as a response to a spiritual hunger that the surrounding culture could no longer satisfy. Read as a whole, the volume is both a description of the initiatory path and a meditation on why that path matters for everyone, not only for those who tread it consciously.
Glossary Terms from this Volume
Thalira's glossary draws on GA 138 for entries that unfold its central ideas in depth. Each of the following terms cites this volume, and each glossary page serves as a hub for the study of that concept:
Eternity and the Passing Moment, The Darkness of Life and the Light of the Spirit.
Following these links lets you move from the broad shape of the lecture cycle to the fine grain of its ideas, and to the further sources and cross-references gathered on each glossary page.
Where to Read It
The full lecture cycle is available in English at no cost. You can read the complete text at the Rudolf Steiner Archive, which hosts the translated Munich lectures of August 1912 in their entirety. For a printed edition, or to compare translations and find related titles, search the catalogue at SteinerBooks. Reading the lectures in sequence, from the first to the last, best preserves the cumulative movement of Steiner's argument.
Continue Your Study
To go further with the ideas in this volume, you can follow several paths:
- Begin with the two glossary entries above, then use the Thalira glossary to trace related terms on initiation, eternity, and the mystery centres, following the cross-references outward to build a fuller map of the vocabulary.
- Explore the wider GA Work Library to see how this 1912 cycle connects to Steiner's neighbouring lecture courses on the Gospels and the Christ event, and how the Munich cycles fit into the arc of his teaching.
- Read Steiner's own guide to inner development before or alongside the cycle, since GA 138 repeatedly points back to it and treats its exercises as the practical ground on which these lectures stand.
- Return to the primary text itself, reading a single lecture at a time and pausing to let each concept settle before moving to the next, so that the cumulative movement of the argument has room to work.
