Sahasrara — Chakra 7 of 114

Sahasrara (सहस्रार) is counted as chakra 7 in the 114-chakra map of the Shaiva Siddha tradition, seated at crown of the head, above the fontanelle. Governed by the tattva of pure consciousness beyond elements, it radiates the hue of luminous white/violet and is sealed by the bija mantra Silent (Visarga/Ah). Its lotus form is described as having thousand petals, and it is presided over by Shiva-Shakti united in non-dual union. Within the subtle body this chakra functions as a node where prana, mind, and consciousness interweave, regulating the flow of shakti along the sushumna and its adjoining nadis. Siddha yogis regard it as a threshold: when dormant it maintains ordinary physiological and psychological function, but when awakened through mantra, mudra, and dhyana it becomes a doorway to subtler states of awareness, dissolving the sense of a bounded, separate self. Tantric and hatha-yogic lineages within Shaiva Siddha describe this centre as storing latent samskaras related to its element and function, and its purification is said to remove specific obstacles — whether physical rigidity, emotional turbulence, or mental dullness — associated with that node. Advanced sadhakas use this chakra as a resting point for kundalini during her ascent, pausing here to stabilize breath and absorb the qualities of its presiding deity before continuing toward the crown. In ritual worship this chakra is also visualized during nyasa, where the practitioner mentally installs mantra and deity into the body to sanctify it as a temple of consciousness.

The yantra of Sahasrara is drawn as a lotus with thousand petals, inscribed with Sanskrit letters proportional to its petals, encircling a central geometric seed-form appropriate to its element — a square for earth, a crescent for water, a triangle for fire, a hexagram for air, or a circle for ether/space centres. At the very centre sits the bija mantra Silent (Visarga/Ah) in Devanagari, often accompanied by the seed symbol or vahana of Shiva-Shakti united in non-dual union, rendered in luminous white/violet against a contrasting field, used as a focal support for dharana and japa.
