What are the small numbers in sentences?

Paragraphs and sentences within paragraphs are numbered with superscripts.  These annotations help students reference specific sections or passages quickly and easily, no matter which edition or format of A Course in Miracles they happen to be using. 

This same annotation (numbering) system also holds true for the many translations of the Course, allowing for cross-referencing of passages between different languages. The first edition of ACIM did not contain the line number referencing system. It was included for the printing of the Second Edition.

The ACIM Annotation System of A Course in Miracles provides a method for students of the Course to reference a specific passage within the Course and its Supplements, concisly and uniquely identifying specific quotes without having to write out lengthy descriptions of where to find them.

Here is an example:

“You will first dream of peace, and then awaken to it.” (T-13.VII.9:1)

• T = Text
• 13 = Chapter 13
• VII = Section VII (of Chapter 13)
• 9 = Paragraph 9 (in Section VII)
• 1 = Line 1 (of Paragraph 9)

Another example:

“We say ‘God is,’ and then we cease to speak, for in that knowledge words are meaningless.” (W-pI.169.5:4)

• W = Workbook
• pI = part I (of the Workbook)

• M = Manual for Teachers
• 4 = Section 4
• X = Part X (of Section 4)
