Explanation:

Ajivika school is known for its Niyati ("Fate") doctrine of absolute determinism, the premise that there is no free will, that everything that has happened, is happening and will happen is entirely preordained and a function of cosmic principles. Ajivika considered the karma doctrine as a fallacy. Ajivika metaphysics included a theory of atoms which was later adapted in Vaisheshika school, where everything was composed of atoms, qualities emerged from aggregates of atoms, but the aggregation and nature of these atoms was predetermined by cosmic forces. Ajivika were considered as atheists. They believed that in every living being is an atman – a central premise of Hinduism and Jainism.
