As it should be!
Do you remember the good ol’ original Aikido and other methods’ “how to,” books each purporting to show “how” a technique should be done?
How many times could you make sense of these photos? Indeed how many time did the editors, non-aikidoka get the sequences right!?
And yet many emerged believing that after have read the book, no, looked at the pictures, they suddenly knew what Aikido was about. And of course, pigs fly!
Knowing has nothing to do with looking at pictures or reading words. These, if correctly compiled, are mere indicators. Knowing means a full absorption of the subject until each and every cell, molecule, atom and sub-atomic particle of your being, physical, mental, emotional and spiritual, resonates in full ongoing and evolving attunement with the subject.
Any idea is merely an idea, an opinion which is usually wrong.
Experience is the only teacher. In order to experience, we must overcome inertia and move; and this with daily regularity.
