Meaning of "O' Sanity" by John Lennon & Yoko Ono

"O' Sanity" by John Lennon & Yoko Ono delves into the internal turmoil of the speaker, torn between embracing madness as a response to the world's calamity or trying to hold onto their sanity despite the overwhelming chaos. The lyrics suggest a sense of helplessness in the face of global crises, with the metaphor of sanity being personified as a restrictive force that the speaker wishes to escape from. The push-and-pull between sanity and insanity reflects a deeper existential conflict about how to navigate a world that often feels on the brink of collapse. The suggestion of using substances to numb the pain serves as a coping mechanism, but ultimately proves to be ineffective as sanity continues to haunt the speaker. The repeated refrain of "let go, let go, cut it out" conveys a desire to break free from the constraints of mental stability and embrace a more liberating, albeit chaotic, existence.
