If you do Aikido, it is your main task to seek aiki, in my opinion.
I disagree...at least, I think that is more true for the "serious" Aikido student. I don't think people have to be looking for aiki above all other things to do Aikido...or at least, that should vary perhaps dojo to dojo.
Is the main task of Chado to make the best possible cup of tea very quickly? Or is it more of an experiential process of being mindful? I think Aikido is, in general, more about the process than the acquisition of aiki.
