V. Whitsun: The Festival of United Soul-Endeavour
This spirit-enlivened ideal was once placed before humanity in a most powerful way. It was when a number of men, all aglow with a common feeling of fervent love and devotion, were met together for a common deed: Then the sign was given, the sign that could show man with overwhelming power how in unity of soul he could provide a place for the incarnation of the common spirit. In this company of souls the same thing was living: in the flowing together, in the harmony of feeling they provided what was needed for the incarnation of a common spirit. That is expressed when it is said that the Holy Spirit, the group-soul, sank down as it were into incarnation. It is a symbol of what mankind should strive towards, how it should seek to become the dwelling-place for the Being who descends out of higher worlds.
