The occult causes

Two Helens, Helena Hahn and Helena Blavatsky,
1844–1845.
According to one of the versions,
the picture was drawn by
H.P. Blavatsky.

Someone left the cake out in the rain/I don't think that I can make it
Perhaps Jimmy Webb's MacArthur Park is as the world's most misunderstood song.
Since you certainly don't understand the lyric, you decided to see what you could find out about the song on the Web, eller Webb.
And then we know there's MacArthur Park, made famous by R. Harris in 1968. but I like Andy´s version.
The song has been ridiculed as classic '60s excess because of the overblown orchestra of the original version and the song's strange lyric--that troublesome metaphor of the cake in the rain, etc. columnist Dave Barry named it the worst song in history, or something like that, a few years ago.
See the below some findings. Each paragraph is a clip from a particular web site with something to say on the subject. Preceding each clip is the link to take you there. In some cases, where copyrights may be involved, I have not included a clip.
Because they were burdened by syrupy orchestrations and recorded by such '70s unhipsters as Glen Campbell, Art Garfunkel and Richard Harris, the songs of Jimmy Webb are often dismissed as relics of an era that produced more cheese than craft.

All very edifying, Jimmy, - but the question that really needs to be asked here is, what are the lyrics to MacArthur Park about? I mean,

Someone left the cake out in the rain/I don't think that I can make it cos' it took too long to bake it and I'll never have that recipe again.

 - what's going on there?
Also I always think that whatever is art, need not and should not be explained, as someone once said.
But I'll tell you: MacArthur Park is clearly about a love affair ending, and the person singing it is using the cake (histroy) and the rain as a metaphor for that.
It was written around about the same time as Strawberry Fields, with LSD, I supposed, so it probably seems a bigger deal now than it was back then.
But still.
Still, the lyric never opened, sure, the cake is some history and it, because the song is grown, refers it to some remarkable thing:   
That thing can be individual´s past life.
If ones have the method, which just calls the memories from past life, until the karma is adapted, peace is gone.
As HP Blavatsky, but also Rudolf Steiner said, the past lives rise to the surface, among other things, the impact of past lives.
