Song meaning of N.I.B. [Past Lives] by Black Sabbath

The lyrics of "N.I.B. (Past Lives)" by Black Sabbath convey a complex message centered around the theme of love and the power it has to reshape one's life. The song begins with the declaration that some people doubt the authenticity of the narrator's love. However, the narrator promises to prove the depth of their love by offering things that were once deemed unreal - the sun, the moon, and the stars. 

The pre-chorus prompts the listener to follow the narrator and leave their previous life behind, as they will be the first to experience this unique and eternal love. The chorus emphasizes the necessity for the listener's love to be real and hints at the intensity of emotions the narrator will experience. 

The post-chorus introduces a twist in the narrative when the narrator reveals their true identity as Lucifer and invites the listener to take their hand. This revelation may suggest the transformative and addictive nature of love itself, which has the potential to bring out both light and darkness within individuals.

Overall, the lyrics reflect a notion that love, regardless of its origin or embodiment, possesses a transformative and influential power that can bring about both joy and turmoil in one's life. The song presents a dark and enigmatic interpretation of love, blurring the line between desire and temptation, and engaging with the concept of embracing one's shadows.
