The force is an energy field created by all living things, it surrounds us, it penetrates us, it binds the galaxy together
The Force is what gives the The August Brotherhood of the Jedi, along with one hundred other traditions, their strength. Though this is a bit of a misnomer, the force connects all living creatures. There is even a heretical Jedi teachings say every sentient being subconsciousness can access the force and may do so more often then they realize.
I’m drawing from the original trilogy force, with a dash of Victorian mysticism and shamanism thrown in. So the powers are more along the lines of E.S.P., supernaturally fast reflexes, and better than average physical abilities, and speaking with the spirit world.
