keep the tension fluid- neither always fully relaxed- or always held
think of the stillness as very active- and maybe give yourself a very long term engaged task
look for the someone in the audience who is... fill in the blank with something really compelling for yourself
the person who I do not know now- but who will be one of my best friends for life... something fun and that provokes you to FEEL and therefore move internally...
In any case, your internal viscera- should be shifting and this will hopefully help make the stillness more alive- also really remember gravity and how much it constantly is changing- don't go numb to gravity- you are still moving, as you always are- but it is just more delicate- great meditative practice!
