What are some other forms of mediation other than your basic "observe your breathing" mindfulness?

Tai Chi Chuan, Qi Gong, and other internal arts are forms of meditation. Under Herbert Benson M.D.'s definition, i.e. repetition of a word, sound, phrase, or movement, while adopting a passive mindset, optimally for 10-20 minutes twice daily these could easily qualify. I generally prefer meditation with movement. And one can always add a word, sound, or phrase to give that monkey mind something to do.

I find walking meditation helps soothe monkey-mind if I’m agitated or anxious, as does weight-lifting to some extent. As the other commenter stated, the act of repetition gives you something to focus on, similar to breathing exercises.
