I need advice here. My former teacher and I no longer train together. When our paths cross we briefly speak respectfully and go our seperate ways. He is a very high ranking practitioner of several arts. His aikido ranking is the least of his ranks. He is shodan. I am shodan. My old training partners are shodan. But my former teacher has promoted another former student he originally promoted to shodan to nidan even though he himself is not nidan. Permissable to promote above your own rank and then have that nidan teach at your for-profit dojo? Please advise. Yours in the honorable spirit of aiki.
