In my experience fasting is like a long meditation. When I go on a meditation retreat and practise for long hours, it is like a journey within myself. Sometimes the weather is pleasant, sometimes not so.
When we fast the mind tends to surrender to a deeper awareness that is beyond our thoughts. Stopping eating is a symbolic act, and is the outer most manifestation of ceasing to hold on to all thoughts, emotions, identities. Then the defenses are lowered and all kinds of unacknowledged, suppressed feelings arise. At the end of the journey we are closer to ourselves than before, more in touch although not necessarily feeling 'better' in the way we would like.
I feel the fast doesn't just occur on the physical level. It also occurs on the level of prana, of thoughts, of emotions, and of awareness. Those are the layers in which Indian philosophy sees the human personality.
And like meditation, fasting can perhaps better be understood as a practice of the mind and body, a way of life, and less so a goal to a particular place. One may get to the goal or one may not, but that is a biproduct.
I wonder if there are many who fast but are not helped in symptom relief, but they cease to post on this forum and other forums because of disappointment and subsequent lack of interest, so we have an over-representation of the successful fasters.
