I just started Contact Improvisation classes and the practise is really amazing. It's a bit like dance with acroyoga, playful wrestling and meditation all rolled into one!

In yoga, we build an awareness of self that is deep and beautiful.... The journey inwards is however done in isolation. With Contact (as in massage work), the meditation is deep but the journey is different as it embraces all that is around us; connecting us with people, objects and the environment - Bringing awareness to a different dimension. Try it out!
I practised contact at various Yoga Massage workshops during the past year but it is great to finally get some formal instruction.
