The lineages
A chain of people who each kept one idea alive.
Advaita was never a single book. It is a succession — teacher to student, for well over a thousand years, through four lines that this family reads from. Where no freely licensed portrait of a teacher exists, the page carries a symbol instead of an invented face.
These are living institutions, not historical curiosities. If any of this lands, go to the source: a Sringeri discourse, a Sunday talk in New York, a Bala Vihar class on a Saturday morning.
