The five aggregates are what a person fundamentally is; understanding them reveals there is no permanent 'self' carrying anything.
The five aggregates (skandhas in Sanskrit) are the five components that make up a living being according to Buddhist analysis. They are form (physical body), sensation (pleasant, unpleasant, or neutral feelings), perception (recognition and labeling), mental formations (thoughts, intentions, and mental habits), and consciousness (awareness itself). The Buddha taught that these five categories account for everything we experience and everything we are.
These aggregates are not metaphorical. They describe actual dimensions of human existence that can be directly observed through meditation and careful introspection. Form includes your body and all physical phenomena. Sensation refers to the immediate feeling-tone of experience. Perception is the mind's tagging and categorizing function. Mental formations encompass volition, emotion, and thought patterns. Consciousness is the bare awareness that registers experience.
The five aggregates relate to what a person 'carries' by revealing that there is nothing separate from them being carried. The question itself assumes a carrier—a permanent self that owns or bears these components. Buddhist analysis dissolves this assumption.
When we speak of carrying something, we typically mean a subject distinct from its burden. But the Buddha's teaching shows that the aggregates aren't things a person carries; they are what the person is. There is no unmixed consciousness separate from the five aggregates that could be the carrier. The aggregates are mutually dependent and interdependent. Remove one component and the others cannot function as they do. This interdependence means no single, unchanging entity stands behind them as an owner or carrier.
The Anattalakkhana Sutta (The Discourse on the Marks of Non-Self) explicitly teaches that each aggregate is not-self precisely because none can be mastered or owned by an independent entity. The Buddha asked monks whether form is permanent or impermanent, whether what is impermanent brings suffering or happiness, and whether they could rightly say 'this is mine, this is I, this is my self.' Since all aggregates are impermanent and conditioned, none qualify as a true self that could possess them.
This teaching applies directly to the notion of carrying. To carry something implies control and ownership—the ability to put it down or take it up at will. But you cannot truly control your body, your sensations, or even your thoughts the way you control a burden. Your body decays despite your wishes. Unpleasant sensations arise unbidden. Thoughts appear without your choosing them. The aggregates happen to consciousness rather than being possessed by it.
In meditation practice, this understanding becomes experiential rather than merely intellectual. When you observe your breath (form), the pleasant or unpleasant sensation of breathing, the labeling mind that notes 'breathing,' the impulses that regulate breathing, and the awareness that knows all this, you see that none of these components answer to a unified command. Each arises according to conditions. There is awareness, but no awareness-owner. There is experience, but no experiencer separate from the experience.
This insight marks the beginning of the path away from suffering, because attachment and craving arise from the false belief that there is a 'me' that needs to secure and protect something. Once you clearly see that the aggregates are not-self, that anxious grasping begins to loosen naturally.
All major Buddhist traditions—Theravada, Mahayana, and Vajrayana—affirm the teaching of the five aggregates and their relationship to the absence of a permanent self. The specifics of how consciousness functions or how the aggregates reconvene in subsequent rebirths differ between schools, but the core principle remains: the aggregates are not carried by a self; they are the totality of what constitutes a being.
