It shows up without an invitation; a formless, colorless
force that makes the soul tremble in delight. It tightens its
grip and imperiously leads. Sometimes it just flirts and
woos, like a teenage girl showing off a new flower in her
hair, and leaving doodles, flourishes and question marks.
Sometimes like a bolt from a dark sky it tears the sleep off
your eyelids. Sometimes a barely visible apparition, it floats
on the horizon and waves from afar. It grumbles, utters
something unintelligible, tousling the senses. It leaves
without a warning.
