The wind howls with mighty force and calmness, displaying the dual principle of nature in action. Much welcome rain brings life to the earth, fills the water tanks and exposes all the poorly maintained house roofs by means of water features, better known as leaks. Business is slow for me this time of year, yet not so for the parrots in my garden, who are frantically occupied harvesting the loquat tree whilst clinging to its erratically swinging branches. I dwell in comfort of warmth and shelter, recovering from knee surgery, enjoying a ‘good time out’, by chance or fate at perfect timing. Whilst in body temporarily disabled, my minds eye’s glass appears neither half full, nor half empty. It is filled to the rim, in that it frees up time to read, write, and to catch up on all the other ‘not too physical’ activities one normally doesn’t have time for, such as the scientific testing of the dual principle of nature, also known as the balance of opposing forces, by means of an alternating full and empty wine glass.
