Relaxation is paramount to opening the door of creativity in any given moment. Tension in the mind and body serves to limit our ability to get "outside the box". In fact, "the box" is made of tension and its resulting contractions at both a mental and physical level. Sometimes we hear of creativity happening as a result of overwhelming tension but I would argue it is when the individual has "surrendered" to their circumstance that the creative solution manifests. This does not mean "giving up" but rather speaks to a deep acceptance of the here and now that opens the door to an unbounded future.
Learning to relax may be the greatest thing you could do to improve your health and quality of life and it may just awaken that creative genius that lies within each of us. You have access to a well of creativity that is only yours and I pray you are able to access it and express it in your life for everyone's benefit.
