Dōhaku

"When there are plateaus to still reach, aim your sights for them and only them. Excite your soul from deep within... and let it all go. Abandon all limitation."

- Seireitou Kawahiru describing the use of Dōhaku.

Dōhaku (動迫, "Motion Spirit"; literally "exciting the soul") is an old technique that forms a pair with Seihaku. Together, they were created long ago by a Hakuda Master focused on developing a method at which a warrior could utilize the latent within their very soul.

Overview
Existing as the polar opposite to Seihaku, the Dōhaku is a technique aimed at exciting the spirit of the user from their very core, allowing for the "activation" of their potential energy; in other words, their latent. It is literally defined as the action of exciting the soul of the user. Dōhaku does not cause all the energy to become used at once, but rather excites the latent reiryoku so that it can be used at a much more beneficial rate, meaning that, in other words, it becomes power prepared for its eventual use.

When in use, Dōhaku causes the reiatsu to take on a much more aggressive form, appearing as jagged flames erupting from the body as the concentration of energy builds up from within. While this is often different in some select few, as Kenpachi Zaraki demonstrated fierce arcs of energy exploding outwards and into the skies, this is due to a lack of experience with the technique. Seireitou claimed that Dōhaku is not an effective tool for battle in the hands of someone who hasn't mastered it, as the exertion of so much latent energy at once could exhaust them at an accelerated rate. However, those that have mastered this technique do not succumb to such a drawback.

Attempting to "power up" using the Dōhaku will only be useful within a reasonable degree, as forcing Dōhaku to continue without having the skill and experience to manage all of the power becoming excited will result in the body becoming weighed down by the output of reiatsu, succeeding in merely weakening the body and soul in the process.
