Rain by The Beatles is a song that metaphorically explores themes of perception and the contrast between inner peace and external chaos. The lyrics highlight how perspective changes everything, suggesting that the 'sun is shining' behind the 'rain'. The song illustrates a shift in consciousness and attitude, urging listeners to look beyond immediate discomforts and external conditions to find inner contentment. Key themes include self-awareness, mindfulness, and the subjective nature of reality. Poignant moments in the song are the repetitive chorus and evocative lyrics which reinforce the idea that inner tranquility can remain untouched regardless of external circumstances.
