As our Persian version of Luminous Journey slowly progresses (after a major change of direction prompted by the Universal House of Justice), we are still interested in pursuing the research and writing of a series of films about 'Abdu'l-Bahá in Europe. While UK has expressed the most interest, France seems to be the starting place for us.
Recently a friend shared the following link, which I am excited about studying:

Hope this will benefit someone who wishes to "go" to Budapest in the footsteps of the Master!
