Ājñā
Third-eye chakra (2-petal lotus)
Ājñā ("command") is the sixth cakra, at the third-eye / glabella. Avalon's v. 32 describes a two-petalled lotus inscribed with हं and क्षं on either side, with the praṇava ॐ as central seed. The yantra is the inverted triangle — the same geometric seal Sat-Cakra-Nirūpaṇa names as the *convergence-point* where iḍā and piṅgalā curve back to meet suṣumṇā (this is the textual basis for the `nadis_yogic` system's convergence-landmark on the same coord). Presiding deity: the *itara-liṅga* (inner jyotir-liṅga); śakti: Hākinī. There is no figural vehicle. Ājñā is the seat of the *rudra-granthi*, the third and last knot a sādhaka must loosen before the bindu of sahasrāra. Vertebral anchor: C1 (atlas, suboccipital). Note that ājñā has no spinous process of its own; the back-view anchor is the height-equivalent of the atlas. Cross-system note: ājñā is identical to the convergence-landmark of `nadis_yogic` — pinning both systems shows the textual relationship between them.
