I will quote O Sensei, the founder of aikido, what i mean about pyramid ( triangle), flower sensation in my belly ( a circle), prayer for the soul , ( square) . So in EE program in my intuition we are constructing aiki ( universal harmony) in our sistem!
O Sensei used three principles to help his students understand the concepts of the movements and techniques used in what they are learning. They are the principles of the circle (marui), the square (shikaku) and the triangle (sankaku). O Sensei was a deeply religious man (although it is emphasized that Aikido is not a religion) and often used these symbols to illustrate some of the principle of ichirei-shikon-sangen-hachiriki, that is One Spirit, Four Souls, Three Fundamentals and Eight Powers which is a framework he believed to be present in every religious cosmology.
One Spirit is the single source of creation and is omni-present, in Aikido it is the seed of kototama SU from which KA-MI (fire and water) arose and thus all other components of existence.
The Four Souls are the
Kushi-mitama associated with heaven and the principle of centralization. This is the source of wisdom, clarity and virtue.
Ara-mitama associated with fire and the principle of industriousness. It is the source of courage, valour and progress.
Nigi-mitama associated with water and the principle of consolidation. It is the source of empathy, trust and respect.
Sachi-mitama associated with the Earth and the principle of differentiation. It is the source of love and compassion
The Three Fundamentals (for which O Sensei uses the symbols of the Circle, the Square and the Triangle) are
Iku musubi (or iku-tama) the vivifying fundamental, it is the dimension of ki-flow symbolizing initiative and Masakatsu. The triangle is the key to entering.
Taru-musubi (taru-tama) the completing fundamental, it is the dimension of liquid symbolizing unification and Agatsu. The circle is the key to blending.
Tamatsume-musubi (tamatsume-tama) the fulfilling fundamental, it is the dimension of solidity symbolizing form and Katsuhayabi. The square is the key to control.
Finally, the eight powers (which sustain creation) being
movement and stillness
solidification and fluidity
extension and contraction
unification and division
“The body should be triangular, the mind circular. The triangle represents the generation of energy and is the most stable physical posture. The circle symbolises serenity and perfection, the source of unlimited techniques. The square stands for solidity, the basis of applied control.”
O Sensei
