So, I got inspired today to write up an acoustic version of this song. It actually
sounds really close to the original; I just didn't bother with the major riffs
and breakdown of the song. Tuned to D Standard, it will match right up with the
recording. 

I fiddle around with hammer-ons and pull-offs with these chords for the intro:

   E   Esus4  E7  E7II
e|-0----0----0----0-
b|-0----0----0----3-
g|-1----2----1----1-
d|-2----2----0----0-
a|-2----2----2----2-
E|-0----0----0----0-

Also, this is the B5 chord I'm using in the chorus; any other B chord doesn't sound right:

   B5
e|-2-
b|-2-
g|-4-
d|-4-
a|-2-
E|-2-

Verse 1:
E5 (play variants through verse)
Since the new world order played upon our fears
Spreading accusations of radical ideas
The brotherhood of wisdom: strength and dignity
Its rituals and secrets remain a mystery

Pre-chorus:
F#                 G        F#                G          F#
  Beneath an ever watchful eye, the angels of the temple fly

Chorus:
B5                   A2
Turn the key, walk through the gate
     G               D       A2      B5
The great ascent to reach a higher state
A2           G      F#
  A rite of passage
     B5             A2
The final stage; a sacred home
   G                  D       A2    B5
Unlock the door, and lay the cornerstone
A2           G      F#
  A rite of passage

Verse 2:
E5                       D5
Men of wealth and power, influence and fame
    C5                        B5
Philosophers and leaders are members of the trade
E5                        D5
Bound by oath and honor, like the rose and cross
   C5                 B5
An enigmatic union of esoteric thought

{Pre-chorus, Chorus}

{do whatever you want for the breakdown here, or nothing at all =]}

Final Chorus:
B5                   A2
Turn the key, walk through the gate
     G               D       A2      B5
The great ascent to reach a higher state
A2           G      F#
  A rite of passage
     B5               A2
The seven stars, the rising sun
   G                   D        A2    B5
A perfect world where new life has begun
A2           G     F#
  A rite of passage
