Śivasaṃhitā 5.129

This verse precisely locates the sahasrāra, the thousand-petalled lotus, within the brahmarandhra at the crown of the skull. This is not ordinary physical anatomy but a subtle topography, mapping the highest point of the energetic body where individual consciousness may dissolve into the universal. The verse functions as a landmark within the broader yogic cartography of the subtle body.

The compound brahmarandhra joins brahman — the Absolute, the expansive ground of all being — with randhra, meaning aperture or cavity. It is literally «the opening into the Absolute». Sahasrāra derives from sahasra (thousand) and āra (spoke or petal), evoking a lotus of boundless luminosity symbolizing fully awakened, unconditioned awareness.

In advanced Hatha Yoga practice, visualization of this lotus at the crown represents the culminating stage of kuṇḍalinī ascent. The Ṣaṭcakranirūpaṇa offers elaborate descriptions of this center. Directing sustained meditative attention here is regarded by the tradition as the threshold between embodied experience and liberation itself.
