Omraam Mikhaël Aïvanhov (1900–1986), French philosopher and educator of Bulgarian origin. Although his work approaches various topics of spiritual science, he clarifies: "With my teaching, I wish to give you essential knowledge about man: how he is structured, his relationships with nature, the exchanges he must make with others and with the universe, so that he may drink from the sources of divine life." From 1937, the date of his arrival in France, until 1985, Master Omraam Mikhaël Aïvanhov provided exclusively oral teaching within the framework of the Universal White Brotherhood. During his lectures (about five thousand), he constantly returned to certain topics: the choices we must make to give meaning to our existence and to develop spiritually. At times, to help us advance on this path, he proposed wishes formulated in the form of prayers. These are the prayers that have been gathered in the fourth part of this book.
