Bravado should not be found in aikido, as it’s all about ego. Showing off is the same thing and is a sign of poor character.
All the true masters in martials arts say this. Technique is merely the way to learn and understand aiki. If you don’t practice aiki you haven’t learnt aikido.
Seen this in aikido. Unfortunate when it’s at the top.
The occasional person in aikido can’t be corrected in technique or anything else. Simple ego and pride and they can’t be reached. Sad when it’s seen in a ‘senior’ student.
Actually, this is fundamental to aikido, but ego or narcissism causes some to lack the courage.
