Meditation techniques, yes, but I don't think there was a chant attached to it. They did have that weird electric sitar music going in the background, though. I thought his crushing the phaser like it was play-dough was pretty indicative of his strength as well.
As much as I love Wrath of Khan, that was the one major thing that I always thought they messed up on - a fight between Kirk and Khan. Or, at the very least, some kind of better interaction than trading jibes across the comm-link.
