Ājñā ādhāra
Brow / command centre
Ājñā is placed at the brow as the upper point of the six-centre Siddha yoga projection, where attention and discriminating awareness are conventionally gathered. This coordinate reflects a cross-textual yoga image rather than a claim that all Tamil Siddha medical lineages use a single brow-centre diagram.
