I want to know the answer to the following question:
What movement focused on the idea that the sould must be freed from matter?
All the background I'm provided with is that "These movements included, besides Buddhism, various skeptics (such as Sanjaya Belatthiputta), atomists (such as Pakudha Kaccayana), materialists (such as Ajita Kesakambali), antinomians (such as Purana Kassapa); the most important ones in the 5th century BCE were the Ajivikas, who emphasized the rule of fate, the Lokayata (materialists), the Ajnanas (agnostics) and the Jains, who stressed that the soul must be freed from matter.". Is that enough to answer the question?
Answer: yes
