Hi , I am late to this thread and new to this forum . I have met the Green Man in mystic meditation and projections with my peers in circle . We have seen him lead us thru the forest and teach lessons on energy , healing and magick . He imho , is also Cerunnos appears as a silver stag in the forest too . There is a guided meditation to meet him by walking into a sylvan forest in meditation and finding a green door standing on the path without walls supporting it , enter in and learn . When touring Ireland I saw images of him on stone walls of churches and on door knockers . In Australia I see images of him on fountains and garden ornaments .
