R is Ruis, the Elder tree, which is connected to the time of the Winter Solstice. The Elder represents endings, maturity, and the awareness that comes with experience. Pronounced roo-esh, Ruis is a sign that things may be ending, but will yet begin again some day. Although the Elder is easily damaged, it recovers and is rejuvenated easily.
The Elder is also strongly connected with Goddess spirituality, and the workings of the Fae. The soft wood has a lightweight core that can be pushed out to create a hollow tube -- perfect for a Faerie flute! Elder was also planted near dairy barns, in the belief that its presence would keep the cows in milk, and prevent collected milk from spoiling. Elder flowers and berries are often brewed to fight fever, cough, and sore throats.
Mundane Aspects: This is a time of transition -- while one phase of life ends, another begins. With maturity and experience comes wisdom and knowledge. Remember that it's fine to be childlike, but not childish.
Magical Aspects: New experiences and new phases of growth are continual, and these will all lead to spiritual renewal, and finally rebirth. Remember that the things we experience are all part of the formation of who we eventually become.
