spontaneus movement, osei



Our organism is not a bundle of cells, tissues, and organs. It is a living being that is formed following a rigourous order, the result of million of years of evolution. It has the capacity to react to different situations in order to keep its own vital balance, it can also adapt to the environment and transform it. Our organism responds to these situations, both internal and external, as a unit because its different activities are completely and absolutely interdependent.

Haruchika Noguchi showed that this capacity of our organism to respond to different situations as a unit arises from the 5 universal movements in + and in –, whether they are under tension or distension. These movements act throughout the different energetic activities (motor, biological, and psychic) of the living being and they form the spontaneous movement.

Osei is the organism’s natural capacity of reaction through the absolute interrelation of its different energetic activities. The osei comprises five oseis + and -, which are the different ways life is manifested.

The vertical osei + and -– (oseis I and II) is essential in the formation of the nervous system and of the sight. It establishes the natural interrelation between:
– the upward movement
– the planning biological activity
– the contemplative or observant psychic activity

The frontal osei + and – (oseis V and VI) is essential in the formation of the muscular-respiratory system and the sense of smell. It establishes the natural interrelation between:
– the unidirectional forward movement
– the metabolic-respiratory biological activity
– the pragmatic or efficient psychic activity

The lateral osei + and – (oseis III and IV) is essential in the formation of the digestive-circulatory system and the sense of taste. It establishes the natural interrelation between:
– the left-right movement
– the assimlatory-circulatory biological activity
– the emotional or mediator psychic activity

The rotary osei + and – (oseis VII and VIII) is essential in the formation of the excretory system and the sense of hearing. It establishes the natural interrelation between:
– the twisting or torsion movement
– the excretory biological activity
– the competitive or resolute psychic activity

The central osei + and – (oseis IX and X) is essential in the formation of the reproductive-subjacent connective system and the sense of touch. It establishes the natural interrelation between:
– the inward-outward movement
– the biological activity of cell regeneration
– the affective or absolute psychic activity

Osei and oseis can be translated into English as reactivity or reactivities. This term is used in Physics, Chemistry, and Psychology to refer to different things. Thus, we use the Japanese word Osei, which has no plural form in this language, so as to avoid any confusion.

On Friday, April 20th, has been the official presentation of the SEITAI Barcelona Foundation. The presentation ceremony was at the Auditorium of the Center of Contemporary Culture of Barcelona (CCCB).

The event was broadcast live.
