I feel like there are people who listen to Beatles songs but don't really take the meaning of their music into consideration. John Lennon claimed there is no need to take most of the band's songs seriously, but I beg to differ. Maybe there was no purpose in the songs lyrics while they were written, but the listener is free to interpret the song and find a meaning of their own.
George's song "Within You Without You" is about embracing love, understanding you're only one person in a world of over 6 billion human beings, your life belongs to you and no one else, everyone's lives are just as important as your own, and everyone is entitled to their opinion as much as you are to yours. Once you understand all this, you will find your own understanding in how the universe works.
Yes, even Ringo's "Octopus' Garden" has a deeper meaning to me. It's a song about loving each other regardless of your differences, and living peacefully and away from what divides you.
Whether you agree with my interpretations or not does not matter to me. You're free to interpret it in any way you see fit for yourself, all that matters to me is for your understanding that the Beatles were a band that provided music that still applies to modern society, and the meaning in their songs' lyrics should be taken more into consideration by the listener.
