Aikido is an experiential martial art. That means that in order to learn it, one must physically experience it.

Nothing replaces "doing" Aikido. However, from time to time, it can be beneficial to look at something in other ways in order to master it. I have found certain books, videos and websites can be of some benefit. I hope that these resources can help you figure out how to better understand the art and help you toward mastering the art of Aikido. Please use them wisely.
