C.G Jung Symbols of Transformation- The Night Journey

[310], Pg 195
The Intrauterine Space/ Sea-faring Histories, Migratory Waters/Channels:
The womb, a common enough conception in the older mythologies.4 The chest, barrel, or basket with its precious contents was often thought of as floating on the water, thus forming an analogy to the course of the sun. The sun sails over the sea like an immortal god who every evening is immersed in the maternal waters and is born anew in the morning. - Jung
