Evanescent

adjective
1.	passing out of sight; fading away; vanishing
2.	ephemeral or transitory When I think of something that is evanescent I think of the gossamer wings of fairies or dragonflies. Something you can see but that is thin and ethereal, flimsy, light, or very delicate. It is a beautiful word that brings to mind beautiful, light and airy creatures of fantasy.

A muse can be any person you meet in your lifetime that opens you up to yourself in a deeper more positive way and becomes the catalyst for change in you. A guiding spirit that brings the best out of you and makes you better and more of yourself than you have ever been. They will definitely be a source of inspiration to you and maybe even encourage YOU to be inspirational for others. Whatever things they bring you can be sure that they are things that help you to learn and grow and be better than you were before they came.  If you are lucky enough to have or find a muse then you should cherish every moment, every lesson. I appreciate MINE and I will ALWAYS.
