relaxing is just relaxing. simple as that when it comes to being in a state of mind.
however, when it comes to body parts such as shoulders,neck hips or even feet, the concept of relaxation and tension takes a very crazy turn.
the body is made of muscles and tendons that envelop,support and even shape the natural skeletal structure. our posture and our actions are thereby shaping our entire being starting from the physical reality.
i would like to mention that muscles opperate on the principles of tension and relaxation, so that when one side is tense, the other is relaxed.
i personally, work very hard to achieve relaxed shoulders that sortof hang down on an open chest that exudes good posture vibes.
however, since a young age i took a closer look at the shoulders and their function, i compared with iaiwaza movements and analyzed the sequences minutely. i came to the conclusion that the ability to tense the shoulders-specifically only one shoulder- was a strength much too valuable and natural to discard. i also discovered such postures in ninjutsu, wrestling and brazilian jujutsu.
so what i am getting at is not that one should tense the shoulders, because i do not mean that that alone is the way, but furthermore, through a lifetime of bad posture in a shoulder or neck or hip, it may not be that easy to stop tensing, because the shape is set. without serious training, stretching and mindful observation of posture, it will not be easy to achieve the relaxation of said areas- it may even require extreme tension in other areas just to hold or attain the position desired.
so relaxation may well be easier for the mind than the body.
