It sounded as if a lady who had money wanted to buy her way into heaven -- with that said, that's about all I understood of the song that seemed rather dark at the seams, with it's mystical, ambiguous language, all the while speaking about "heaven".
That being said, some meanings embedded in this song became obvious to me in the mid 1970s.
Surprisingly, the comments do not address some metaphorical or metaphysical aspects, and do not consider important cultural movements that were contemporaneous during the time of the initial creation and release of Stairway to Heaven.
But what still puzzled me was that there were some key words on the lyrics of the songs on that album released by Led Zeppelin in 1971. Our lives reflect what we continually think about, all the things we take in, such as food, TV, ideas, beliefs, habits, people.
For example, the word 'Book of love' on the song 'Rock n Roll', or the last song of the album 'When levee Breaks'. This thread is full of people with different backgrounds and mindsets.
What if that the press wrote a headline that says 'The Day The Music Die' and that two young men knew about this tragedies and thought they wanted to write a song about this each other.
