I thought ki was fake.
Before I took Aikido I took Karate at a commercial competitive dojo. Then I took baguazhang, or however you spell it, under a skilled master with not so skilled assistants. Then one day a friend handed me "The Art of Peace" and showed me some youtube videos.
After a few months I found the right dojo and my friend gave me his dogi. After a few lessons I realized that ki was real.
After a while I began to understand how to use ki a little bit.
Recently I have become aware of my center, and I haven't even been to my dojo in a while. I've only used one point meditations and practiced with my friend on the cold hard ground outside.
First I though ki was fake then I misunderstood what my center is, I hope I gain even more insight.
Looking back I think I could have learned a thing or two about ki and my center from the baguazhong, but it didn't click until I took Aikido. Have any of you had an experience like mine?
