The Scorpio period of the year (at least in the Northern Hemisphere) is the time when the life force withdraws from all outer forms in nature and is concentrated in the seed. It is striking that the cultural symbol for this time of the year in the United States is the Halloween pumpkin with its insides removed, leaving only an empty shell with a blankly staring face. In fact, the jack-o-lantern is a symbol of death, a symbolic skull with the glimmering remains of the departed life force represented by the candle within it. Traditionally, the Halloween feast (the Eve of All Saints Day) was a time when the dead came back to life and when human beings in the physical body could most immediately contact departed spirits of all kinds, as well as their own patron saints. It is significant that children are allowed at this time to wander out at night, past their usual bed time, and that they are not supposed to go from house to house begging for food until the Sun (the symbol of physical life) has completely set!
