Ocean
The ocean is the beginning of life on Earth, and symbolizes formlessness, the unfathomable, and chaos. The ocean can also be seen as a symbol of stability, as it can exist largely unchanged for centuries. The ocean is considered to be boundless, a place where one can easily be lost, and can therefore be seen to represent the boundless span of life, and the way one can get lost on the journey through life.

Water: Water popularly represents life. It can be associated with birth, fertility, and refreshment. In a Christian context, water has many correlations. Christ walked on water, and transmuted it into wine, thus these acts can be seen as a transcendence of the earthly condition. Christians are baptized with or in water, symbolizing a purification of the soul, and an admission into the faith. However, water can also be destructive (as in the biblical flood which only Noah and his family escaped); water drowns and erodes, wearing away even the densest of stones given enough time. Water is also one of the four elements essential to life in traditional western philosophy. In this form it is represented by undulating lines, or a triangle pointing down. Colors commonly associated with it are blue and green. Its qualities are fluidity and cohesiveness. Flowing water usually represents change and the passage of time.
