Swing

Myths, folklore, & symbolism
Swing: In Southeast Asia (and to some extent in Greece and Spain), the swing is associated with fertility rites. The motion of swinging is related to the ebb and flow of natural growth and possibly to the earth-fertilizing wind (which can arise from swinging). Especially in India it symbolizes the setting and rising of the sun, the rhythm of the seasons, and the eternal cycle of death and birth; it sometimes also represents the harmonious union of heaven and earth and thereby occasionally the union of the rainbow and rain.
