Beatles lyrics?

From “Across the Universe” – does anyone know what the chant at the end means? They are singing something that sounds like “Jai guru deva om” so I assume it has something to do with their Maharashi days.

Here’s one explanation.

Apparantly it’s a Sanskrit phrase which loosly translates to “I give thanks to Guru Deva”.

Unfortunately, the phrase doesn’t translate well and there is a tad of controversy over what it precisely means. It’s a kind of prayer, I feel.
