However, the science of Esotericism—the inner or secret science—differentiates between "return to embodiment" and "reincarnation/transmigration."

The first refers to the higher, rational human soul wearing a new human body (exclusively human) upon its return to Earth, while the second refers to the possibility of the rational soul transitioning into a human, animal, plant, or inanimate body.

This heptad is composed of two groups:

A higher trinity.
