Four pillars standing outside the gates — a Digambara feature, and not part of the reckoning this atlas follows.
One before each entrance. The name says what they are for: the sight of them is said to humble the pride of anyone who approaches carrying it.
The Śvetāmbara accounts this atlas draws from do not include them. They are recorded here because they appear in almost every image a reader will find, and their absence from the map would otherwise look like an omission.
