Seijō Reiryoku

Seijō Reiryoku (清浄霊力, Clean Spiritual Power) refers to spiritual energy that is drawn in by a Seijin-trained Shinigami from said Shinigami's environment and then molded into the Shinigami's existing source of reiryoku, creating a far cleaner, much "brighter-feeling" energy, which is the source of a Seijin's power. Achieving such reiryoku takes about two years to learn, and ten more to master. This is usually done by having Seijin Masters pass knowledge on to a pupil, as it is impossible for a regular Shinigami to self-teach themselves to use it. After the establishment of the Order of the Seijin, more Shinigami gained access to this power if they were in the Order itself.

Seijin Masters and Grandmasters are capable of creating this energy without even thinking about it, due to their great skill. Lower-class Seijin require varying degrees of focus to achieve the same result.

It has been noted that once one achieves this energy, it is theirs for life and cannot be taken from them in any manner. For that reason, should a Seijin go renegade, the Order moves quickly to kill them, to keep the danger from spreading.

Shiro Nagare
Shiro Nagare (白流れ, White Current) is the term used to describe the applied use of seijō reiryoku. Once a Seijin can access this power, he or she can shape it into various techniques that extend their Shinigami powers to the maximum, essentially creating "Perfect Shinigamification". This is achieved through a Training Method known as Control (管轄, Kankatsu). Even after learning how to access seijō reiryoku, a Seijin cannot fully control it, therefore it leaks out profusely. With meditation and practice, a Seijin can better control seijō reiryoku, effectively mastering it, though this require several years of work. It provides the following enhancements;


 * Enhanced Reiryoku Sensing: Through the use of Shiro Nagare a Shinigami can sense reiatsu and reiryoku from all four dimensions; Soul Society, the Spirit King's dimension, Hueco Mundo, and the World of the Living. They can also sense presences hidden by kidō, zanpakutō, or even other Shiro Nagare-enhanced techniques.


 * Enhanced Flash Steps: By combining the practices of Shiro Nagare with Flash Steps, a Shinigami can reach speeds that dwarf those of the Shinigami in Onmitsukidō.


 * Telepathy: Using Shiro Nagare practices, a Seijin can communicate with other seijō reiryoku users via mental telepathy. This comes in handy during combat.


 * Telekinesis: The most common use of Shiro Nagare practices among the Seijin is the power to lift objects according to concentration and move them, hovering the items in any direction. With it, a Seijin could attract objects to them or repel objects with devastating effects, even to the point of neutralizing some energy techniques. They can also use it to call thier zanpakutō back to thier hands wherever they may be.

Influences
This type of reiryoku was inspired by Sage Chakra from Naruto (also known as Natural Energy), as well as the Force from the Star Wars universe.
