We have just received the following information from Sripad BV Nemi Maharaja, one of the organizers of the Volgograd festival:

Dear Kishore Krishna Prabhu,

Please accept my dandavats. All glories to Sri Sri Guru and Gauranga.

It is definitely confirmed that Srila Gurudeva will not be coming to
Russia for the festival, following advice from his doctors in Houston, and the
festival has been cancelled altogether.

It has not been possible to arrange any alternative festival. This was finalised while I was in Holland and
two or three days later.

Aspiring for service to Sri Hari, Guru and Vaishnavas,
Bhaktivedanta Nemi
