Commentary

In the majority of vital point charts from China and Okinawa, that are available to the general public, Seidon pressure point will either not appear or is depicted as the human eye it self by most writers. This depiction, is in my viewpoint, an error, for several reasons. 1) If the eyeball is hit directly the eyeball will turn to one side or the other, in turn it would be impossible to cause the effects and or results listed on the original Asian charts. 2) If the eyeball could be hit directly it would cause a lacerated eyelid and a rupture to the eyeball with a possible protrusion into the gelatinous matter beneath, In turn causing temporary to permanent blindness, which may or may not be corrected with surgery. 3) A strike to the eyeball, although is not a true pressure point, it will lower the heart rate of the person which is hit. This in itself would also not cause the effect and or result listed above. 4) The weapons list above from Hohan Sokan’s Charts, Wouldn’t cause damage to the lid or eyeball except the one finger fist. 5) it is stated on the original chart of Hohan Sokan’s That it is a double vital point, above and below the eye.

The first of the two point is and extra ordinary point which is named Yuyao. Its location is at the midpoint of the eyebrow. You can feel a little indent there. It has no real application with in the martial arts, on it’s own. Its medical purpose is to be needled subcutaneously 0.3 to 0.5 inches, when there is pain in the supra orbital or there is cloudiness of the cornea, redness, swelling, twitching in the lids and or pain in the eye. Using Acupressure, pressing with the opened hand can also help to relieve congestion of the sinus cavity.

Stomach # 1 (St# 1) name: Chenqi meaning, holds tears, is located with the eyes looking forwards, is directly below the pupil at the infra orbital ridge. Its medical use is to needle slowly puncture perpendicularly 0.5 to1.0 inches, for redness swelling and pain of the eye, lacrimation, night blindness, twitching of the lids and facial paralysis. This pressure point is not only difficult to hit but when hit, can cause a range of reactions. A light strike will cause the eye to tear and swell with possible black and bluing. It can cause the recipient to feel sick and extremely weak. A harder strike can produce from dizziness to unconsciousness.

Seidon which is the combination of the two points, Yuyao and St # 1, from master Hohan Sokan’s vital points chart, is struck simultaneously, with a palm heel or elbow, knee, head butt or the like. These weapons were given to the intermediate ranked students the advanced students would strike Seidon with a shuto strike. And can be combined with other strikes to produce a more perilous out come, which will be discussed in a up and coming editorial on combination vital point at a later date.

The type of weapons listed above, other than the knee, would be difficult to use for these reasons. The palm heel strike actually strikes only with the bottom bony part of the inner hand, located above the wrist. The elbow strike has a tendency to strike the eyeball it self, its the same with the one finger strike. In my opinion the Shuto or the Hand Knife is the preeminent strike to be used for Seidon because the Hand Knife in the upright position can strike both Yuyao and St #1 at the same time.

The use of the Shoto can be seen in the Shorin Ryu Kata Hakutsuru and in the Shaolin forms Lien Bu Chuan, Gung Li Chuan, Yi Lu Mei Fu, Shaw Fu Ien and Shih Tzu Tan. Any Kata or Form that demonstrates a double augmented block also may be used to strike Seidon. In this application, the lower arm is the blocking arm as the upper arm strikes with either a Back-Fist or a Shuto. When using the Back-Fist, strike with the middle (long) fingers knuckle and finger joint. Warning Like all vital points a Super hard strike may cause death to the one hit. Be careful this point is tricky, and has many health risks as well.
