Emptiness (sūnyatā) explains the nature of everything. The explanation was already implicit in the earliest teaching of no-self (anattā) – that humans have no permanent, unchanging ‘self’ (or soul), but instead consist of five aggregates: the body, feelings, perceptions, mental formations, and consciousness. Another early teaching looks to the nature of experience, concluding that nothing exists independently, but rather arises (and ceases) through a web of connected causes and conditions. This is Dependent Arising (pratītyasamutpāda).

The Marks of Existence (impermanence, unsatisfactoriness and no-self) describe all phenomena; the Four Noble Truths diagnose the human condition, account for our suffering and prescribe a remedy. But descriptions alone don’t explain why things are as they are. For that, we turn to emptiness. It provides a remarkably simple answer, but it took centuries of development to formulate, even though the answer was implicit in those earliest teachings.

The aggregates are no‑self: they have no fixed core. The same is true of all phenomena. What appears stable is only a set of conditions. When the conditions change, the appearance changes. This is dependent arising, and it entails that nothing exists independently. Emptiness is the name we give to that absence of independent existence, but the English word ’empty’ really isn’t a good fit for sūnyatā, because it obscures at least as much as it reveals. Emptiness isn’t a void or nothingness; it isn’t an empty container; it isn’t clever metaphysics; and it’s not a denial of conventional reality.

While dependent arising entails that nothing we experience exists independently, emptiness isn’t ultimately a conceptual property like ‘absence of independence’ – for any such definition would turn it into a thing to grasp, and emptiness dissolves all such grasping. Emptiness isn’t a property added to phenomena; it’s the absence of any fixed essence in the first place.

So what’s left? Emptiness is just the mode of existence of all phenomena: thus.

Thusness, sometimes called suchness (tathātā), simply describes how all things are, free of labels, thoughts or judgment. There’s no mystery, no metaphysics, no doctrine: just the mode of existence of all things and in plain sight. A title that the historical Buddha used of himself, Tathagata, relates to the same root – it means ‘one who has gone to thusness,’ or simply ‘one who abides in things-as-they-are’.

I write this sitting at a table; it has every appearance of being solid and self-contained. If I take it apart, either physically or metaphorically, I find it is made of parts, conditions, concepts, functions and histories, but I don’t find the essence of my table. And if I press on, I find that every part has further parts, every condition rests on other conditions, every concept I have of it consists of other concepts – I can never find the table; nothing that represents a unique “tableness”.

And yet I sit at it. Plainly, it exists conventionally, but it doesn’t exist independently. This is emptiness. Emptiness that is neither concealed nor a mystical secret; not discernible only through rare attainments – its nature is obscured by the tendency to grasp, fix and solidify that which is fluid. Emptiness is startlingly simple. Clarity solves everything, not by adding anything, but by removing the insistence that things are other than they are – and they are thus.

This is the middle way: not eternalism (“the table truly exists”); not nihilism (“the table doesn’t exist”), but the simple fact that the table exists dependently – in emptiness.

So it is with all things. And if you truly see this, it quietly reshapes everything.

Everything.

Four – Seeing Clearly

1. Three Marks of Existence (1 Jul)
   • You look at impermanence, unsatisfactoriness, and no‑self with modern honesty: they seem obvious, overstated, or already accepted – so where’s the profundity? You explore the possibility that the Marks aren’t mystical at all, but simply the texture of ordinary experience. Awakening may be less revelation than recognition: nothing hidden, nothing dramatic, just reality seen without dressing it up.
2. Four Noble Truths (15 Jul)
   • A critical, modern look at the Four Noble Truths: you set aside metaphysics and monastic authority, treating the Truths not as propositions to believe but as a doorway into practice. Zen’s refusal to “believe,” Batchelor’s Four Tasks, and the traditional formulation all serve the same function – orienting attention toward the Eightfold Path, where the real work of ethics, meditation, and clarity begins.
3. Emptiness (29 Jul)
   • A plain, modern explanation of emptiness: nothing has a fixed essence, everything exists dependently, and “thusness” is simply things as they are when grasping falls away. Not nihilism, not metaphysics – just the absence of independent existence in all phenomena. Seeing this clearly reshapes everything, not by adding insight but by removing insistence.
