本书的论述涉及三类内容。第一类是构成此项功修的前提条件，辨明这些条件是履行此项功修所必需的。第二类是关于构成要素（arkān）的内容，这些既包括必须亲身践行的规定，也包括必须舍弃的事项。第三类是关于相关事宜的内容，即针对各项行为的律例（aḥkām）。事实上，每一项功修都可以看到是由这三类内容构成的。

The discussion in this book is related to three categories. The first category comprises things that form the preliminaries of this worship, and' whose identification is necessary for practising this worship. The second category is about things that constitute the elements (arkdn), and these are prescriptions to be acted upon themselves and things that are to be relinquished. The third category is about things that relate to associated matters, and these are the ahkdm for the acts. In fact, each worship can be found to be constituted by these three categories.
