When we are looking for stability in our spiritual journey, the example of a sufi whirling comes to mind. I used to do the sufi whirling meditation and I remember the times when I would be whirling and feel an incredible sense of stillness, of absolute stability within my mind.
Those few moments of an empty mind was enough to convince me that meditation is the way forward if we want to have stability. In the midst of movement, of the daily hustle and bustle, I was to function from that stillness. However, to stabilize in this practice, you need to do it diligently everyday, otherwise it is was very easy to lose such progress.
Nourishing an element of inner awareness is the simplest thing to do but the most difficult to maintain. Hence, true spiritual attainment is available only for the few that are willing to give their all to the practice.
