Shamanic journeying

There are many ways to enter into a shamanic state of consciousness...through dance or repetitive movements, listening to repetitive sounds , becoming inwardly still....it just takes time and practice...i would only journey on someone elses behalf if they had made this request...have fun going within.

Some of these - for example becoming inwardly still - do not have the boundaries of other methods. What are your safety measures? I take it you would only do this with a carefully worded intention?
