The differences in language cause disunion between nations.
There must be one universal language. The diversity in Faiths is also a cause
of separation. The true foundation of all faiths must be established, the outer
differences abolished. There must be a Oneness of Faith. To end all these
differences is a very hard task. The whole world is sick, and needs the power
of the Great Healer.

London’)
