The Yuga and the Cycles of Time: Are We at the Twilight of an Age?

One must begin with an important clarification. The elaborated doctrine of the four Yugas, those great cyclical epochs of cosmic time that Hinduism developed in the Puranas long after the Rig Veda, does not yet exist in its complete form in the Vedic hymns. The Rig Veda does not speak of Krita Yuga, Treta Yuga, Dvapara Yuga or Kali Yuga with the precision and systematicity that the later tradition would give them. But something essential is already there, in the Vedic text, that prefigures and nourishes this vision: the awareness that time is cyclical, that civilisations and epochs are born and die according to rhythms that surpass ordinary human history, and that the present moment is situated within a larger arc whose understanding is necessary for acting with wisdom.

The word yuga itself appears in the Rig Veda in a more general sense than the one it would later take on: it designates a generation, an era, an age, a bond or a joining between periods. The root yuj, meaning to join, to connect, is the same as that of yoga. A yuga is a joining in time, a moment when something ends and something begins, when one epoch closes and another opens. This vision of time as a succession of joinings rather than as a continuous linear flow is fundamentally different from the modern vision of time as continuous progression toward a better future.

In the oldest hymns of the Rig Veda, awareness of cyclical time is expressed above all through natural cosmology: the cycle of day and night, the cycle of the seasons, the cycle of the years with their renewal of the sacrifice. Ushas arrives every morning, identical and new, carrying the same promise in a form that is always unprecedented. The sacrificial fire is lit and extinguished according to a rhythm that reflects the cosmic cycle. The rivers swell and decline according to the cycle of the monsoons. Vedic civilisation lived immersed in these natural cycles in a way that our era has largely lost, and this immersion in the cycles of the natural world nourished an intuitive awareness that time is not an arrow but a spiral, that what seems to end returns in another form.

The tenth mandala, composed in the period of crisis that followed the disappearance of soma and the beginning of the drying up of the Sarasvati, bears the first traces of a more explicit awareness of cyclical decline. One senses in it a melancholy, a nostalgia for something that is receding, an awareness that the world of before no longer exists and that the world to come is not yet clearly visible. It is the feeling of the end of an epoch, and this feeling is universal: every civilisation that has passed through great transitions has experienced and expressed it in one way or another. The tenth mandala is the Vedic testimony of that particular moment when a civilisation knows it is in the process of transforming without yet knowing into what.

The elaborated doctrine of the four Yugas, which would take its classical form in the Puranas and in the epics, says that cosmic time unfolds in cycles of four ages of decreasing duration and quality. The Krita or Satya Yuga is the golden age, the age of complete Truth, in which human beings live in perfect accord with dharma and the fundamental reality of the world. The Treta Yuga is the silver age, where Truth begins to decline. The Dvapara Yuga is the bronze age, where half of the Truth is lost. And the Kali Yuga is the iron age, the dark age, the age of conflict and confusion, in which we live according to this tradition, and which will end in a dissolution before a new cycle begins.

This cyclical description of time has something profoundly different from the linear vision of progress that dominates Western modernity. In the progressive vision, history moves from barbarism toward civilisation, from ignorance toward knowledge, from poverty toward wealth, from violence toward peace. Each generation is supposed to be more advanced than the previous one. Catastrophes are accidents, deviations from the general trajectory of progress, temporary setbacks in a globally ascending movement. In the Vedic cyclical vision, there is no permanently ascending trajectory. There are cycles, phases of expansion and contraction, ages of clarity and ages of darkness, and each phase has its own logic, its own characteristics, its own challenges.

What makes this vision particularly interesting for our era is that it offers a framework for understanding what the progressivist vision struggles to explain: why, despite centuries of scientific, technological and institutional progress, does the world seem to be heading toward crises of growing scale and complexity? Why does knowledge increase but wisdom not follow? Why does material wealth accumulate but the meaning of life not deepen? Why do institutions multiply but trust diminish? The Vedic cyclical vision would say that we are in a phase of contraction, in the descending part of a cycle, and that this phase has characteristics of its own that neither will nor technology can simply cancel out.

But it is necessary to be precise about what this vision is not. It is not fatalism. It is not an invitation to resignation, to passive waiting for the cycle to end so that things will improve. The Vedic tradition, in all its expressions, insists on the fact that even in the most difficult phases of a cycle, the path toward the Truth remains accessible. Brahman does not disappear during the Kali Yuga. The dissolution of the ego remains possible. The direct experience of Reality remains within reach of those who seek with sufficient intensity and perseverance. What changes from one yuga to another is the difficulty of the path, the density of the obstructions, the intensity of the effort required. In the Satya Yuga, the path was wide and direct. In the Kali Yuga, it is narrow and strewn with obstacles. But it exists.

The question that the title of this article poses deserves a direct answer, even if it is uncomfortable. Are we at the twilight of an age? There are in what we observe around us sufficient convergent signs for the question to be taken seriously. Climate disruption, growing inequalities, the erosion of institutions, the fragmentation of collective identities, the loss of common meaning, the multiplication of conflicts: all of this resembles, in the description that the Vedic tradition gives of the Kali Yuga, the characteristics of an end of cycle. Not the end of humanity, not a definitive and irreversible catastrophe, but the end of a way of organising collective life and humanity’s relationship with the planet and with itself.

What comes after the end of a cycle, in the Vedic vision, is not nothingness. It is renewal. The Kali Yuga ends in a dissolution, a pralaya, a return to the undifferentiated state from which a new Satya Yuga can be born. This dissolution is not necessarily catastrophic in the sense of total destruction. It can be progressive, partial, selective: certain structures, certain ways of living, certain worldviews dissolve to make way for others. What we call today transition — whether the energy transition, the democratic transition, the transition toward other forms of economic and social organisation — is perhaps the contemporary form of this cyclical renewal that the Vedic tradition describes with cosmological imagery.

What the Vedic cycles of time ultimately offer us is perhaps less a precise description of our historical moment than an inner disposition. The disposition of someone who knows that ends of cycles are moments of intense transformation, that the dissolution of what was is not only a loss but also a liberation, that something new is preparing itself in the darkness of what is ending. This disposition does not suppress the urgency of acting, does not diminish the necessity of responding to the crises with all available intelligence and energy. But it situates this action within a larger framework, it gives it a depth of perspective that can be the difference between the panicked action of a being who sees only the catastrophe and the lucid action of a being who sees both the catastrophe and the renewal it announces.
