Mabon, Wednesday, September 23, 2015 at 4:22 AM , marks the second and final time (the first was March 21st) each year that day and night are of equal in length. The autumn day's grow shorter, the nights longer. Now, is the time when the Earth prepares for the departure of the sun's abundant light, warmth, and growth. The planet enters the time when the darkness takes over the light. Tuning into the seasonal activities, the wheel of life connects one with the universal rhythm. Life is continuously changing, evolving, dying, and being re-born. Summer is fading. In the orchards apples dangle, red, gold and ripen. Harvesting the vegetables begins, with tomatoes, squash, cucumbers, beans, potatoes, corn, and all the rest pouring from the garden. We reap what we have sown. http://www.witchskel.com/mabon.html

This is the Pagan Day of thanksgiving. Any festival of Thanksgiving that may have been celebrated in the new World's Plymouth Colony quite possibly grew out of this original Pagan observance, as the Pilgrim's gave thanks for the success of their previous year's crops. As Pagans, we thank the Goddess for Her abundance of the year and for Her blessings, with part of Mabon ritual feast typically dedicated to the Goddess as sacrifice that is purely symbolic. The sacrifice is the spirit of vegetation.
Take a moment to say thank you for the unanswered prayers in your life. The people, place or thing you prayed for in earnest. If you had received it...you wouldn't be where you are today.
