Sunday 7th October, though some sources say Monday 10th October, is Going Forth of Isis (Aset) in Egyptian Tradition. Apparently, her heart is pleased on this day because 'the heritage is granted to her son Horus (Heru)'.
On this special day, a specially selected team of Priests and/or Priestesses would commence a procession to take their most treasured image or statue of Aset (Isis) to another temple, with many planned stops en route. At each stop a sacred rite would be performed by the Priests/Priestesses and often divinations would be offered. When the final temple destination was reached, the image or staue would be placed in an honoured location and a joyful fesival celebration would ensue.
Informative posters of Isis, as per the sample shown here, are by Jacqui Taliesin El Masri from Alkhemi.co.uk. Laminated versions of this and other Egyptian Posters by Jacqui, are available to purchase from the Harmony Shop.
