General overview of Summerland in Neopaganism
The common portrayal of the Summerland is as a place of rest for souls in between their earthly incarnations. Some believe that after one experiences life to its fullest, and has come to know and understand every aspect and emotion of physical human life (usually after many reincarnations), their deity will allow them to stay in the Summerland for an eternal afterlife, although this belief is not universal amongst Neopagans. Another common element is that the soul has little, if any, recollection of the Summerland once it arrives on the mortal plane again. The Summerland is also envisioned as a place for recollection and reunion with deceased loved ones.
As the name suggests, it is often imagined as a place of beauty and peace, where everything people hold close to their hearts is preserved in its fullest beauty for eternity. It is envisioned as containing wide (possibly eternal) fields of rolling green hills and lush grass. In many ways, this ideology is similar to the Welsh view of Annwn as an afterlife realm. However, the Summerland is also viewed as the place where one goes in the afterlife in traditions of Spiritualism and Theosophy, which is where Wicca got the term.
