Ask when Buddhism began and the answer is a lifetime: the Buddha’s, in the sixth century BCE. Ask when Christianity began and the answer is a birth, a ministry, a death. Ask when Sanatan Dharma began and the honest answer is that the question is malformed. There is no founder to name and no year to point to, and this is not because the record was lost. It is because the tradition has never claimed to have started.
Sanatana means without beginning and without end, and the word was chosen deliberately by people who were perfectly capable of writing history when they wanted to. The Puranas record dynasties, the Mahabharata records a specific war, the astronomical references in the Vedas can be dated by the position of stars. This is not a culture indifferent to chronology. It simply places dharma itself outside the category of things that have a chronology, on the reasoning that a truth discovered is not the same kind of thing as an institution established.
The claim is that the sages who composed the Vedic hymns did not invent what they wrote. They are called rishis, seers, and the verb used for what they did is closer to seeing than to authoring. What they saw, the tradition holds, was already the case before anyone saw it, the way a law of nature is already true before it is measured. A founder makes something new exist. A seer reports something that was already there.
This is a strong claim and the tradition does not pretend otherwise. It also has a practical consequence that runs through everything else in this series: because Sanatan Dharma does not date itself to a founding event, it never had to freeze at that event. Traditions built around a founder tend to treat later addition with suspicion, since anything the founder did not say is automatically secondary. A tradition built around ongoing discovery has no such ceiling, which is part of why it kept producing new philosophical schools, new commentaries, and new saints for three thousand years without ever declaring itself finished.
What follows in this series is not a history lesson, because there is no starting line to walk back to. It is closer to a description of a pattern that these texts claim was always running, watched by successive generations from different angles. The rest of this account starts, appropriately, not with a date but with a question: what was there before there was anything.
