Nishio sensei regarded every irimi entrance as giving the attacker a chance to stop the attack and retreat. This way, he saw aikido as a forgiving budo. His way of doing the aikido techniques usually contained not just one, but several moments where the attacker had a chance to halt and step back.
And he specifically pointed out these moments when he demonstrated techniques? Could you give an example, maybe a specific technique? I ask not to challenge the concept, but to understand it better.
