Living Force (Earth-2356)

"All energy from the Living Force, from all things that have ever lived, feeds into the Cosmic Force, binding everything and communicating to us through the midi-chlorians. Because of this, I now can speak to you."

- Yoda's Force spirit

The Living Force is an aspect of the Force labeled by Hagoromo Ootsutsuki, the first one to understand and teach the mystery of the midi-chlorians. The teachings of the Living Force, distinct from the Cosmic Force, were meant to give people a better understanding of themselves, as well as others, and lead the galaxy into an era of peace. It made possible the phenomenon of Force spirits.

The Living Force would eventually come to be known as simply the Force, a more weaponized version of the Sage of Six Paths' teachings.

Overview
Hagoromo Ootsutsuki exemplified his teachings by distributing midi-chlorians meant to "connect" people's spiritual energies with one another. It would allow people to understand each other without communication and pray for one another's safety. After being passed over as the successor of the Living Force over his brother, and subsequently, Indra Ootsutsuki was the first to weaponize it into Force techniques. Others followed his footsteps, using midi-chlorians to connect their inner spiritual and physical energies together instead of each other. It was Hagoromo's belief that no one's midi-chlorians should be so much greater than any other. If the power is accumulated into one person, then it increased the possibility that the person would become arrogant and desire even greater power, succumbing to the dark side. In the end, they ended up using their midi-chlorians in battle, just as Hagoromo's mother Kaguya did. Yoda was considered a student of the Living Force and eventually stressed its importance to his former Padawan, Tsunade, telling her that being mindful of the Living Force required him to keep her concentration on the here and now, rather than letting anxieties about the future come at the expense of the present moment.
