You are made up of both Prakriti (the Divine energy and intelligence that governs the existence and functioning of the Creation) and Purusha (the Universal Self that pervades all of Creation). Now this takes us to another topic altogether. So there are certain qualities (Gunas) such as Sattva, Rajas and Tamas, and you act according to these qualities.
If you have more of Tamoguna, you will move towards violence. If you have more of Sattva, you will move towards harmony. If you have more Rajoguna, you will struggle with activity; in between the other two states, so there might be a little peace and a little violence. That is just how things are.
