The Secret Doctrine of Goddess Lalita
(Sri LalitaAṣṭottara Rahasyārthamu)
34. bhavachakra pravartinī
She who keeps the wheel of birth and death rotating.
The word bhava in this nāma means birth or saṃsāra. saṃsāra is the wheel of worldly existence that rotates endlessly. This empirical world is called saṃsāra because the jīvā thinks it is helplessly trapped in the endless cycle of birth and death.
In reality, there is no wheel called saṃsāra. It is parāśakti, the Supreme Power, that creates the illusion of a jagat and jīvā. She plays this game in two ways. As jagadātmika, She is the wheel of saṃsāra. As jaganniyāmika, She is the one who keeps the wheel turning. Therefore, Devī is both the operator and the operation of the world.
What is really present is parāśakti alone. Incapable of grasping the truth that Devī Herself is appearing as saṃsāra, we imagine that saṃsāra is real and that Devī keeps the wheel of saṃsāra rotating. Conforming to the our limited understanding, Devī conceals Her true nature and continues to appear as saṃsāra.
