Serge Fitz thank you for having introduced in France the knowledge of Grabovoi Gregori and his work. Interesting and accessible if somewhat scattered in its content. The passages on the resurrection of the dead take up much space and an own experience of the author with his deceased uncle. I personally have appreciated a stronger development of the "philosophy" of GG, mainly on what he says about the need to include in itself (in the cells of the body) eternity and infinity. In this perspective, the daily exercises proposed by GG in his small eponymous booklet are an important contribution to our collective evolution
