This particular book is also helpful in that editor/translator David Godman (who has produced other excellent advaita texts) has grouped Ramana's teachings by subject, and has himself prefaced many quotes with an explanatory preface.

It also has a more useful subject index than the index in Talks with Ramana, and has a glossary of Tamil and Sanskrit words.

Ramana's teachings (usually Q-and-A) are interspersed with verses by poet/disciple Muruganar, but these verses are really optional reading since they merely attempt to reflect what Ramana says (much more clearly) by his own tongue. With the verses passed over, the books is basically a short version of an addenda to Talks with Ramana, though some of the material appears in both. There's also a bibliography, for those who insist on more reading!
