The Majjhima Nikaya avoids the contradiction by denying a permanent self while accepting causal continuity through dependent origination.
The Majjhima Nikaya teaches anatta, or non-self—the doctrine that there is no unchanging, independent essence within persons. Yet it also clearly describes rebirth: consciousness arising in new lives, karma bearing fruit across existences, and beings progressing toward enlightenment over many lifetimes. How can experience continue without a self to experience it? This apparent contradiction puzzled ancient Buddhist philosophers and remains challenging for modern students.
The Buddha directly addressed this in the Majjhima Nikaya. In the Potthapada Sutta (MN 54), he explicitly rejects the idea that consciousness is eternal or transmigrates as a unified entity. Instead, he describes consciousness as conditioned and dependent, arising fresh in each moment according to conditions.
Rather than positing a self that persists, the Majjhima Nikaya explains continuity through dependent origination (paticca samuppada). This is the principle that all phenomena arise in dependence on conditions. The Mahatanha Sutta (MN 38) shows how craving conditions grasping, grasping conditions becoming, becoming conditions birth, and so forth. Each link causes the next without requiring an entity that passes through them.
Crucialy, the Majjhima Nikaya treats rebirth not as a self relocating, but as a process where the dying consciousness conditions the arising of new consciousness in a fresh stream. The Milinda Panha, later commentary, compares this to a candle lighting another candle: the flame continues, but no flame passes from one to the other. The Majjhima Nikaya itself avoids such metaphors and stays focused on the actual mechanism—causal conditioning without a causal agent.
The Majjhima Nikaya consistently analyzes persons into five aggregates: form, sensation, perception, mental formations, and consciousness. In the Anattalakkhana Sutta (MN 22), the Buddha teaches that none of these aggregates is the self. More importantly, the aggregates themselves are in flux—they arise and cease moment by moment. What we call 'a person' is simply this continuously changing collection.
Across lifetimes, there is no unchanging person, yet there is clear continuity in the aggregates themselves. Mental formations (the fourth aggregate) particularly preserve patterns—habitual actions, intentions, and dispositions. These are not a 'self' storing memories; rather, they are conditions that naturally shape how consciousness arises in the next life, just as yesterday's habits naturally influence today's behavior.
The Majjhima Nikaya explains rebirth through karma (kammic action), not through a transmigrating soul. The Samyutta Nikaya companion texts make this explicit: karma is the seed, and rebirth is the fruit. Importantly, the text teaches that intention is the core of karma. In the Nibbedhika Sutta (MN 101), karma is described as the action's natural fruition—not punishment or reward administered by anyone, but the inevitable unfolding of conditioned phenomena.
When a person dies with certain intentions, dispositions, and mental habits, these do not vanish. They are conditions that shape the next arising of consciousness. There is clear causality and responsibility, yet no need for a substantial self bearing karma. The being who acts and the being who experiences the result are connected by conditioning, not identity.
The Pali Canon, including the Majjhima Nikaya, leaves certain details unexplained. Different Buddhist schools have interpreted the mechanism differently. Theravada tradition emphasizes that the final consciousness at death directly conditions the arising of consciousness in a new rebirth. Mahayana traditions introduced concepts like Buddha-nature or the alaya-vijnana (storehouse consciousness) to explain continuity more concretely. These later developments go beyond the original Majjhima Nikaya but attempt to clarify what the early texts left implicit.
The original texts remain consistent: there is no unchanging self, yet experience and responsibility continue through natural causal laws. This is not mystical. It is simply the recognition that persons are processes, not entities, and processes can condition other processes across time without needing a permanent thing to link them.
