 Each Epistle starts by stating its particular goal. All of them contain a core of technical teachings and a conclusion regarding the haqîqa, the inner meaning of the contents. The texts contain frequent invocations to the learning “brethren” – that is, the elect who are studying the sciences – that enhance their didactical and exhortative style; these invocations mean that the students will be awakened “from the sleep of matter and the negligence of ignorance” if they apply themselves assiduously to study “with the assistance (ta’yyid) of a spirit coming by God.”
