Bhagavan composed a series of verses entitled The Necklet of Nine Gems. The first verse describes the relationship between Arunachala Siva and Nataraja Siva. “Siva as Nataraja is one who churns and whirls the energies of the universe around Himself. He creates and destroys the universe through the pulsation (spanda) of his universal will while he abides unmoving (achala) in the heart — the centre of the circle of energy (shakti) which encompasses him. Siva as Arunachala is the still point and according to Bhagavan, stillness (achala) means perfection or knowledge (jnana). Why? There is no movement in the heart space and therefore it is timeless, eternal. If one were to follow through the logic of this, it is fullness (purnam). He is One, he is Achala.”
