I thank the great Masters that left us the registration of the Universal Truths, through which I could elaborate my concept on Theosophy.


I thank my son Roberto who besides the incentive that transmitted me along all these years of planning and execution of the texts, patiently and tirelessly, worked in the fingering in the computer, structuring and final formatting of the book.


I thank my son Marcos for the valuable suggestions that he gave me.
