Introduction (from the Padma-purāṇa)

[Note: this book was extracted from the translation of The Padmapurāṇa]

From the preface of the eighth volume:

The last ten chapters of this part praise the first ten chapters of the Gītā and show how a recitation of each wholly or partly, intentionally or accidentally elevates a wretch to the highest spiritual position. While praising chapter sixth for its efficacy the famous Chāndogya story of king Jānaśruti and sage Raikva is reproduced with a slight variation in these names making them Jñānaśruti and Raikya respectively.

From the preface of the ninth volume:

The first eight chapters eulogize the saving power of the last eight chapters of the great Bhagavadgītā supported by illustrative stories.
