The song "Circles" by George Harrison reflects on the cyclical nature of life and relationships. The lyrics suggest that friends come and go, and that love and opinions can change over time. The line "He who knows does not speak, he who speaks does not know" implies that those who are truly wise often remain silent, while those who talk may not necessarily possess true knowledge. Harrison further explores the concept of reincarnation, stating that the soul takes on a new body with each birth. With life and death being constant companions throughout the journey, the soul continues to incarnate and repeat the cycle. This idea highlights the continuous cycle of existence. The song also emphasizes the unpredictability of relationships. Disliking someone at one point does not guarantee that the same sentiment will be held forever. People may change, and enemies can become friends. This further exemplifies the circular nature of life. Towards the end, Harrison suggests that when we reach a state where we no longer focus on loss and gain and can accept the ups and downs of life as the same, that is when we break free from the cycle and stop going in circles. Overall, "Circles" explores themes of change, relationships, wisdom, and the perpetual cycle of life and death.
