Spiritist Knowledge

Broadly speaking, mediumship can be defined as a person's ability to get in touch with the spirits. This concept follows very closely a famous definition made by A. Kardec in his treatise on mediumship, published in the heyday of Spiritualism. At the time, it was clear that mediumship manifestations could make use of external objects (as in the case of the celebrated "table-turning" or more generally in the haunting phenomena) or simply transmit elaborate information through the so-called "intellectual mediums".

Since then, names like Konstantin Raudive (1909-1974) and Hans O. König are linked to the history of EVP as relevant researchers who recorded many clear voices which cannot be explained away easily. In what appeared to be an acceptance of something already known, ...

But, soft: behold! lo where it comes again! I'll cross it, though it blast me. - Stay, illusion! If thou hast any sound, or use a voice. Speak to me! W. Shakespeare, Hamlet, 1.1 My nephew XK lives in the US and is a young American who speaks both Portuguese and English. Driven by his love for singing, he was alone at home recording songs with a Karaoke system. Careless about one of his recordings, he left the recorder on a little longer. To his surprise, he noticed an unexpected voice at the end of one of the files. After inquiring the unseen to give him and his mother a reply, the unusual voice appeared a second time. Fearing the invisible, he abandoned his karaoke sessions since then. Fig.2 Filtered waveforms of AV1 in the indicated interval showing the anomalous voice. My sister sent me two of ...
