Just as electrical energy produces heat, sound or light depending on the device through which it passes, similarly, the energy of consciousness functions through three different but closely connected entities, the mind, intellect and personality.
With the power of the mind, one imagines, thinks and forms ideas. The non-physical mind should not be confused with the heart, the physical organ that maintains blood circulation.
The intellect understands, reasons, memorizes, discriminates and makes decisions. The non–physical intellect should not be confused with the physical brain, which is the physical focus of the nervous system.
Habits and sanskaras are all embedded in the soul in the form of impressions as a result of every action performed. The most fundamental feature of every soul, its personality, is determined by such stored impressions.
