Sacred Dimensions of Time and Space — Tarthang Tulku: time, space, knowledge, and experience

A book that begins with the fact that we are here

The book’s structure is strikingly systematic. It is divided into three major parts — SPACE, TIME, and KNOWLEDGE — each containing eight chapters. The titles make clear that this is neither standard metaphysics nor simply a meditation manual. Under space we find Geometry of a Living Universe, Cone of Possibilities, Structure of Zero, and Space Qualities. Under time appear Life Time, Ordinary Time, Space-Time Partnership, Depth of Time, and Power of Time. Under knowledge we find Structures of Knowledge, Orders of Knowledge, Cone of Knowledge, Zero of Knowledge, Freedom of Sixteen, and Transition to Knowingness. [3]

That structure already expresses the central movement of the TSK approach. Tulku does not ask only “what is space?” but “how does space participate in the arising of experience?” He does not ask only “what is time?” but how our way of experiencing time shapes the possibilities and limits of life. And with knowledge he does not stop at what a person knows, but investigates the act of knowing itself. [1][5]

TSK is not a new religion

Tarthang Tulku comes from Tibetan Buddhist culture and is an important Nyingma teacher in the West. Yet the language of the TSK series is deliberately unusual: it does not require the reader first to accept Buddhist doctrine, God, an absolute substance, or a hidden creative principle. TSK’s own presentation explicitly says that it does not put forward claims about an absolute and does not define a particular substance or one final reality that the reader must accept in advance. [4][5]

That does not mean the project is disconnected from Buddhism. Its author, its mode of inquiry, and its distrust of rigidly fixed selves and objects have an obvious historical background. But TSK attempts to turn that background into a language of open inquiry that can also work for a reader who does not use Buddhist terminology. The first volume of the series, published in 1977, was already presented as an investigation of fundamental dimensions of experience without requiring a specific religious perspective. [6]

Space is not merely a container

In ordinary thought, space is often treated as an empty three-dimensional box in which objects are placed. The chapter titles already point toward another view: space can be approached as a field of openness, possibility, appearance, and relationship. Cone of Possibilities, Magical Body of Space, and Manifestation of Form are not terms from a physical theory; they are attempts to make the reader notice how form appears within openness and how space participates in differentiating what we experience. [1][3]

From this perspective, an object is not a fully self-contained thing that is only later placed in space. Its appearance is spatial from the beginning: it has location, relation to other things, boundaries, direction, and possibilities of movement. These features can be examined directly in experience without turning them into a claim about what the universe is “really” made of.

For that reason, the title Geometry of a Living Universe is best read as the author’s conceptual geometry of experience, not as a new geometry of the astronomical universe. [1][3]

Time is not merely the clock

Similarly, the book distinguishes Life Time from Ordinary Time. The titles alone indicate that the author is not interested only in time as a measurable quantity. Time is also the way experience is arranged: we anticipate, remember, hurry, postpone, feel limitation, duration, or openness. [3]

Chapters such as Endpoints of Time, Back to the Beginning, Dimensions of Time, Depth of Time, and Power of Time explore different ways in which time structures presence and meaning. [3][5]

This difference matters. Physics can measure intervals, compare clocks, and model spacetime. TSK asks what it means to be a being whose life is always already temporal: something has happened, something is happening, something is possible. The two kinds of inquiry may use some of the same words, but they are not the same discipline.

Knowledge is not something we simply possess

The third part of the book may be the most radical. The publisher’s description opens with the idea that systems of belief are “the tracks that knowledge leaves behind,” whereas direct questioning offers another relationship to knowing. [1][2]

Such a formulation distinguishes knowledge as content from knowledge as the activity of knowing. The first can be recorded, categorized, and stored. The second is happening now, in the encounter between what knows and what appears. It is therefore significant that the closing chapters do not culminate in a list of answers, but in the title Transition to Knowingness — a transition toward the very mode of knowing. [3]

This does not imply that facts or arguments are unimportant. Rather, the book challenges the moment when our labels and theories become more important than the inquiry that gave rise to them. In this sense TSK is above all a methodological challenge: can we use concepts without immediately turning them into a closed world?

Why zero, cones, and sixteen?

The most unusual part of the book is its use of geometrical and numerical imagery. Descriptions of the book explicitly mention zero, ratio, cones, and the number 16, while the table of contents includes Structure of Zero, Cone of Possibilities, Cone of Knowledge, Zero of Knowledge, and Freedom of Sixteen. The book also uses numerous diagrams as visual metaphors for new ways of thinking about space, time, knowledge, and the arising of experience. [1][3]

This is where misunderstanding becomes easy. Because geometrical and mathematical terms are being used, a reader may begin to interpret them as claims of mathematics, physics, or numerology. The publicly available descriptions do not justify that. It is much safer to understand them as conceptual and visual models by which Tarthang Tulku tries to interrupt our habitual ways of organizing experience.

“Zero,” then, is not treated here as a hidden cosmic constant, the “cone” is not a new geometry of spacetime, and “sixteen” is not a demonstrated law of the universe. They are parts of the book’s internal architecture whose fuller meaning can only be judged honestly by reading the specific chapters and diagrams. [3]

A Buddhist book without mandatory Buddhist terminology

This is precisely where Sacred Dimensions becomes interesting in the wider THY-REALITY framework. Its aim is not to replace Western science with Tibetan cosmology. TSK instead attempts to create a language in which readers can investigate the structure of their own experience without first accepting an entire Buddhist metaphysics. [5][6]

At the same time, complete separation from its Buddhist background would be equally misleading. Distrust of fixed identities, emphasis on direct inquiry, and the movement from possessing knowledge toward knowing itself can also be understood within the broader history of Buddhist philosophy and contemplative practice.

The fairest description is therefore double: TSK emerged from a Buddhist intellectual environment, but it was formulated as an independent language of inquiry intended to be accessible outside religious affiliation as well.

What the book actually asks of the reader

The publisher says that the book invites the reader into an inquiry capable of personal transformation, while its diagrams function as visual metaphors for new ways of thinking. [1][2] That is a very different promise from the promise of a scientific book.

A scientific theory must offer measurable predictions, procedures of testing, and the possibility of independent refutation. In the publicly available descriptions, Sacred Dimensions primarily offers experiments with ways of seeing, conceptual frames, and experience. Its value is therefore first of all philosophical and contemplative.

If a reader comes to experience space, time, and knowledge less rigidly, the book has achieved what it places in the foreground. It does not follow from that, however, that it has demonstrated a new physics of time, an objective architecture of the cosmos, or a universal theory of consciousness.

A geometry of experience

The title Sacred Dimensions of Time and Space can sound as if the book is revealing hidden dimensions of the cosmos. Its actual project is at once more modest and more demanding. Instead of telling us what we must believe about the universe, it asks how much of the “universe” we live is already shaped by the way we use space, time, and knowledge. [1][5]

In this sense its “geometry of meaningful existence” is not a map of invisible worlds. It is an attempt to map the arising of meaning itself.

If that distinction is preserved, the book becomes interesting without exaggeration. Not as alternative physics, but as a question: what happens to the reality we live when space, time, and knowledge stop being treated as self-evident?
