When I learned Ikebana as an adult, I was really fortunate to have had an old_fashioned sensei (instructor) who not only taught me the theory and techniques, but also immersed me in the respectable manners and ways of the good old days. It is through my sensei that I learned that Ikebana goes beyond the typical art form, and that it is more of a way of life; in fact, Ikebana is also known as kado, which literally means "the way of the flower."
