This lovely song was originally written and sung by the late, great Carl Wilson - with some of the other Beach Boys pitching in. For starters, it's a paean to the benefits of Transcendental Meditation. Thematically it presents the idea that everything in our world is interconnected and that to grow as a person, one must be open to experiencing multiple ways of perceiving yourself and the world you live in. And I think there’s a little ‘As Above, So Below’ in there too.

Lyrics

All This Is That
I am that, thou art that and all this is that
I am that, thou art that, all this is that
I am that, thou art that, all this is that
This is that, ooh
Daybreak and I take a glide
Into the pool of peace inside
Two waves and I, both travelled by
Life supporting waves of bliss
Mother Divine's precious kiss
Brings with love the light of wisdom
And the gift of eternal freedom
To waves and I, both travel by
And that makes all the difference to me
All this is that
I am that, thou art that, all this is that
I am that, thou art that, all this is that
This is that, ooh
Dusk time, the shadows fall
Into the timeless time of all
Two waves and I, both travel by
Golden auras glow around you
Omnipresent love surrounds you
Wisdom warming as the sun
You and I are truly one
Two waves and I, both travel by
And that makes all the difference to me
I am that, thou art that, all this is that
I am that, thou art that, all this is that
I am that, thou art that, all this is that

Jai Guru dev, Jai Guru dev
Jai Guru dev, Jai Guru dev
