The Narada Bhakti Sutra (IAST: ) is a well known sutra venerated within the traditions of Hinduism, reportedly spoken by the famous sage, Narada. The text details the process of devotion (Bhakti), or Bhakti yoga and is thus of particular importance to many of the Bhakti movements within Hinduism. It has received particular attention among the Vaishnava traditions. Sanskrit scriptures often appear in variant editions which may show differences in organization and verse numbering. For example in the translation by Swami Prabhavananda there are eighty-four verses arranged in nine chapters, whereas in the Bhaktivedanta Book Trust translation by A. C. Bhaktivedanta Swami Prabhupada and his disciple Satsvarupa dasa the eighty-four verses are organised into five chapters. As organized by Swami Prabhavananda, the text covers the following subjects: Chapter 1 (verses 1-6) provides a definition of bhakti. Chapter 2 (verses 7-14) stresses the importance of renunciation and self-surrender. Chapter 3 (verses 15-24) provides exemplars of divine love. Chapter 4 (verses 25-33) endorses bhakti as the highest goal of human life. Chapter 5 (verses 34-42) provides suggestions on how to practice divine love. Chapter 6 (verses 43-50) explains the importance of seeking holy company. Chapter 7 (verses 51-57) discusses the difference between preparatory and supreme devotion. Chapter 8 (verses 58-73) covers the forms of divine love. Chapter 9 (verses 74-84) recommends the practice of ethical virtues and worship of God. In the translation by Bhaktivedanta Swami Prabhupada the chapters break at similar points, but with the first four chapters arranged into double the amount of verses: Chapter 1 (verses 1-14) The Value of Devotion Chapter 2 (verses 15-33) Defining Bhakti Chapter 3 (verses 34-50) The Means of Achievement Chapter 4 (verses 51-73) Pure and Mixed Devotion Chapter 5 (verses 74-84) Attaining Perfection Key Concepts Within the text Narada explains the perfectional stage of pure devotion; the process to achieve this state; gives quotations from other Vedic personalities on the subject matter; things to avoid when developing bhakti; and finally explains the nature of selfless love and the different forms of attachment to the Supreme person. Pure devotion Firstly bhakti itself is defined as being "the most elevated, pure love for God" which is eternal by nature and through following which one obtains perfect peace and immortality (release from samsara). The symptoms of such devotion are that one no longer has any selfish desires, nor is affected by the dualities of loss or
