I relate very much to the Knight of Swords as it relates to Gemini, my Sun sign. According to Roman Mythology these inseparable brothers were considered the patrons of horses, a majestic creature I greatly love and adore.
Castor the mortal, and Polydeuces the Divine represent courage, adventure and change. Having a sense of adventure and being open to change can make us better people. When we can temper our intuition/emotion with our rational/intellectual mind and visa versa, this can help us to be aware of our behaviour and our mortal/divine nature.
This card brings to mind the Winter Solstice, with the presence of both light and dark in our lives.
Like the twin brothers it is a good reminder to me that I can't have one without the other, and I've learned to appreciate both individually, and simultaneously.
I hope you are looking forward to the future with adventure and change and I pray that you have courage.
