In this book - first published in July 2017 - the first three works of James Allen have been compiled, translated by the same translator into Greek for the first time during the period 2014-2016, with improvements made where necessary. James Allen, the self-illuminated philosopher, the pioneering author of self-help books, and the inspirer of all subsequent self-help book authors, envisioned a society of people free from its wounds. However, such a society can only exist through the discovery and revelation of the path by which each of its members can be freed from their own wounds. Thus, James Allen wrote a series of books so that his knowledge and experiences could be put at the service of humanity, particularly the vulnerable human being.
