Sahasrāra
Crown chakra (1000-petal lotus, stylized as 32–40)
Sahasrāra ("thousand-petal") is the seventh cakra, at the crown of the head. SCN proper enumerates six bodily centres (mūlādhāra through ājñā); sahasrāra appears in the commentary tradition (Avalon ch. on "the cerebrum," pp. 141 ff.) and in later texts. The classical figure is a thousand-petal lotus inscribed with the full Sanskrit syllabary 50 × 20, with no fixed seed-mantra — the bīja here is *parā-nāda*, the unspoken silent sound. There is no presiding deity, no vehicle, no granthi: sahasrāra is the destination of the kuṇḍalinī ascent and the union-point of Śiva and Śakti. The site on the body is the *brahma-randhra*, the aperture above CROWN_VERTEX through which the yogi's awareness is held to exit at mahāsamādhi. The 7-system project renders sahasrāra as a stylized radial bloom of 32–40 visible petals (the count is symbolic in the text); the reading-panel label remains "1000-petal lotus." Lineage tie-breaker: the post-Theosophical "violet crown" colour code is treated as a variant rather than adopted.
