Jai Guru Deva om

It was said in the beatles song "Across the Universe". Most simple translation is:

"I give thanks to Guru Dev (heavenly teacher) om"

Om is just a sound. However a more detailed translation is:

"Jai" means "O Hail" or "Victory to"
"Guru" means "Teacher"
"Deva" means "God/Lord/Demi-God"
"om" some say is the source of all existence that comes from vibration

Note Guru Dev was a Maharishi's teacher

From the ancient Saskrit language.

It means "Victory to God Devine", most accurately. "OM" is the vibration of the universe, with which one who meditates desires to be in tune.

From the Famous Beatles song 'Accross the Universe'

Translation from Sandscript:

Jai translates to praise or honor.
Guru translates to teacher.
Deva translates to Godess.

Deva in 'Across the Universe' ends in A in this song. Actual translation is femine. (i.e. Goddess)
Goddess is the Divine Mother of the Universe (hence Across the Universe)

Om of course is the sound of the universe resonating all around us.

Jai Guru DevA Om
Nothing's gonna change my world.

I don't want you to understand a word I am saying, so I will pretend I am from a different country.
