The expression MAZAL TOV is a Hebrew locution that translates as "good luck". It is a wish that is expressed aloud in Jewish celebrations and its meaning is "I am looking forward to good things happening to you". If we explore the deep meaning of each of the consonants that make up this word, we will access the true secret of prosperity. The hidden keys in the word Mazal indicate that luck does not come "from above" but depends on our effort in three coordinates that should be known and put into practice. In this illuminating fable, Francesc Miralles offers us a fascinating and practical journey into the secrets of success.
