I've been reading elsewhere that there is a method of communicating by those in this world with their departed loved ones.

It's said that a device has been invented by spirit scientists and is being used by Portugese speakers in Brazil. It provides a way for spirits to communicate their thoughts through the device to their loved ones still alive. The thoughts are changed to a vibration that interacts with electronic equipment in this world. The reverse happens for those communicating from this world. It's called 'Instrumental TransCommunication with Stations' and work is being carried on to create another communication station but for English speakers.

Will you please tell us what you know, Sparrow, or what you can find out about this?
