There is only your soul and the karma that attaches itself to your soul. So the ultimate purpose in Jainism is to cleanse your soul so clean that you can achieve nirvana and escape this cycle of reincarnation. Yes, they believe in reincarnation and they don't want to keep coming back. They want to free their soul to connect with the one universe to achieve what they call moksha. Now, the Jainists have a very elaborate and complex system of the universe that they believe in. They actually believe in three universes, but that blew my mind so I can't talk about that. But I can talk about the official symbol of Jainism, which is right there.
