Sine waves can be seen as a metaphor for the cyclical nature of life. Just as a sine wave oscillates between positive and negative values, life is characterized by a series of ups and downs, with moments of joy and happiness alternating with moments of sorrow and pain. Additionally, just as sine waves can be combined to create more complex patterns, the various experiences and events of life can be seen as building blocks that come together to create our individual and collective narratives.

Sine wave is a representation of the balance in nature. The sine wave is always equal to zero at its midpoint, meaning it is a balanced wave. It also oscillates between positive and negative values, representing the balance of good and bad in life.
