From the correspondence of Stoyan Mihaylovski

The epistolary heritage has, as is well known, an important significance for illuminating the personality of a given social, political or cultural figure, for revealing his "peace of mind", the motives of his actions, etc., as well as for filling in the gaps or correcting the inaccuracies made in his biography. This is especially true for the period of formation, maturation of the creative personality, for which period there is usually very scarce or uncertain information. Hence the justified interest that is shown in the correspondence of prominent personalities both by the researcher and by the wide circle of readers.
