Furyoku

Essential to even the most basic shaman magic, furyoku (巫力, furyoku?), meaning "shamanic power", is the measure of the sixth sense that an organism is born with. It is generated by willpower and its integrity is contingent upon the being's conviction, but is can be created either naturally or artificially (ie. the Golem). Every living thing (plants, animals, and human beings) is given a measure of furyoku by the Great Spirit prior to birth to live out their lives, and upon their death, that power then returns to the planet. During an organism's lifetime, they have experiences from which they gain memories, and once they die, their furyoku returns to the planet, taking with it the memories of the life form to which it had been attached. These memories in turn give rise to more furyoku, allowing the planet's spirit as a whole to grow, and the cycle of life to continue.

Furyoku can also be increased, but much like the five basic senses (sight, hearing, touch, smell, taste), furyoku is an inborn power that cannot be improved merely through physical training. The process for increasing a shaman's furyoku usually involves a "pseudo-death" experience. Ventures such as these usually involve the shaman being stripped of their physical senses, leaving only their sixth sense. Throughout the ordeal, the shaman must contend with the onslaught of negative emotion from their own being, relying only their strength of heart sustain them. After such an ordeal, the shaman's soul would either be strengthened or broken, in which the shaman may never recover. Senses are the physiological methods of perception. ...

Nonetheless, it's essential that a shaman rigorously engage in acquiring more furyoku
