Reader friend:
This book has not been written with letters, but with the heart. Therefore, it is advisable to read very slowly.
A quick read will make the concepts listed here seem incoherent: you will feel that you are going from one topic to another without a thread that unites them. However, this stems from the reader's attitude regarding the way in which he unravels the wisdom that is hidden in each of the chapters.
Although it seems paradoxical, here no conclusions are given; they must come from inside the reader. For this, it is necessary to study hard and scrutinize each of the phrases; In this way, they can be given a personal meaning, which will make it easier to apply them to one's own life, making the most of them. In fact, each reader will reach a different level, according to his capacity for deepening and the time he dedicates to it. The most important thing therefore is that, before moving on to the next topic, all the concepts described are weighed internally to assess whether they were integrated into life, not only in theory, but in practice.
