This was Harrison's first single as a solo artist, and it was his biggest hit. The song is about the Eastern religions he was studying.
Highly unusual for a hit song, Harrison repeats part of a Hindu mantra in the lyric when he sings, "Hare Krishna... Krishna, Krishna." When set to music, this mantra is typically part of a chant, that acts as a call to the Lord. Harrison interposes it with a Christian call to faith: "Hallelujah" - he was pointing out that "Hallelujah and Hare Krishna are quite the same thing."
In the documentary The Material World, Harrison explains: "First, it's simple. The thing about a mantra, you see... mantras are, well, they call it a mystical sound vibration encased in a syllable. It has this power within it. It's just hypnotic."
