I just heard an amazing version of this song on KBS (Korean radio). It was more like a full choral version. I wish I could find it, but I didn't catch the name from the broadcaster.
Hayley Westenra sings Heaven, Heaven.
Baha'u'llah describes the departed ones as forming a Concourse on High. A concourse is
- A large open area inside or in front of a public building, as in an airport or train station: "the domestic arrivals concourse".
- A crowd or assembly of people.
Of course, the people are our family members and friends who have passed on.
Such is the station ordained for the true believer that if to an extent smaller than a needle's eye the glory of that station were to be unveiled to mankind, every beholder would be consumed away in his longing to attain it. For this reason it hath been decreed that in this earthly life the full measure of the glory of his own station should remain concealed from the eye of such a believer.(Baha'u'llah)
The song lyrics must therefore be true about meeting up with loved ones in the post-terrestrial life.
