"Brainwashed" is the final track of the posthumously released George Harrison album, bearing the same name. It should be noted that, throughout his years, Harrison was a spiritual person, and a self-admitted creature of probable religious contradictions, due a keen interest in both Christianity and Hinduism. Nonetheless, he stayed true to his convictions through to his last breath, and this song is just one indication of that. "Brainwashed", whose lyrics at first appear seemingly mundane, takes on a readily-apparent transformation into something of a prayer.

The song (and thus album) ends with a bhajan chanted together by George and Dhani Harrison; I've read that, translated, it reads something like the following:

Sing the name of the Goddess Parvati, who removes afflictions.
Sing praises to the Divine.
Praise, Praise be to Shiva the Great God.

...although I've also heard that, based on pronunciations ("hara" versus "hare"), it could be a prayer outright to Shiva, husband of Parvati.
