This article emphasises the need of calming our heart and mind in line with the writings of the philokalic authors. This can be done by contemplating the little things like the color of the sky and of the stained glass, the irisations of a peacock tail and of the opal, the glow of beetles and of gold nanoparticles, the smell of incense and myrrh, the structure of the lotus leaf and of a wax comb. In a grain of sand we can find the essence of the world and we can find ourselves.
Keywords: nanotechnology, structural color, emergent order.
