This book contains aphorisms, phrases and poems that Monsignor Federico Kaiser wrote for his nuns, but it is addressed to all those who want to use these pages. Its name is “ESTRELLITAS” (little starts), it is about little lights that are numbered, but without order of succession or system, in a similar way to the stars sown in the night firmament. These “modest lights” have the intention of giving a formative, orienting or encouraging value. Sometimes a biblical place is indicated, in order to facilitate the reading of what he wanted to write.
