Jenjei (Earth-2356)

Jenjei is one of the three main Force technique categories. Jenjei is the most nebulous of the three, and may most simply be described as anything that is not genjei or taijei. All jenjei require use of the Force and hand seals. The huge range of jenjei's uses is illustrated by its several sub-classifications: medical jenjei, reincarnation jenjei, space–time jenjei, barrier jenjei, sealing jenjei, and cursed seal jenjei.

Most jenjei use shape transformation, which deals with controlling the form and movement of the jenjei, while nature transformation deals with changing the jenjei's physical properties. Jenjei that use nature transformation tend to follow a naming convention of their nature type followed by a more specific name. With practice and experience, certain jenjei could become second nature to a Jedi, allowing them to perform it at will.

The simultaneous use of jenjei and taijei is called jentaijei.
