It was written at the end of 1867 or in the beginning of 1868. Without being an artistic work, the lines in his unfinished autobiography reveal Levski’s participation in the First Bulgarian Legion, his role of a standard-bearer in Panayot Hitov’s detachment, show his rich mentality, prove his endless courage.
There are many missing pages in the pocket notebook of the Apostle. It contains facts about his organizational and political work. There is information about his tours around the country between 1871 and 1872, as well as a report on people’s money that he had spent. It also reveals his modest preferences about food, clothing and his attraction to folk song and revolutionary poetry.
Levski left one hundred letters handwritten by him that are addressed to some prominent contemporaries and companions of him, to the Bulgarian Revolutionary Central Committee in Bucharest or to some private committees on the territories of Bulgaria. These letters prove his extremely hard-working nature, major intentions and unique deeds for the welfare of his country.
Vasil Levski’s political and national conceptions are even more clearly represented in the ideological, political and organizational documents: “Instructions of the workers for the Liberation of the Bulgarian People”- a handwritten by him draft regulation, programme and laws for the revolutionaries’ actions.
Many of these unique documents are being kept in Cyril and Methodius National Library. Only a few of them which are written or signed by Levski are kept in other institutions – in the Scientific Archive of the Bulgarian Academy of Sciences, in the State Archive in Veliko Tarnovo, in the museums in Lovech and Pleven.
