BG Chap 12 - Bhakti yoga
In this chapter, Kṛṣṇa says that among all processes, pure bhakti, having the greatest power, enables one to quickly attain the Lord. The superiority of all types of devotees to the jñānīs is described, and among the devotees those who are endowed with wonderful qualities like lack of hatred are praised.
In the second and consequent chapters (2-6), one particular path was described in which after one understands about and realizes the jīvātmā, one then meditates on the Lord, the aṁśī. A second path was shown in the seventh and subsequent chapters (7- 11), in which, after understanding that the jīva is an aṁśa (dependant and servant) of the Lord, one meditates upon the source of the aṁśa, the aṁśī, the Supreme Lord, by the process of bhakti (BG 7.1). In those middle six chapters, bhakti mixed with yoga (BG 8.10), and jñāna mixed with bhakti were also described (BG 9.15). At the end of the sixth chapter, before the middle six chapters, with the verse yoginām api sarveṣāṁ (BG 6.47) the pure bhakti of those exclusively attached to the Lord, who were also the best among all, was described.
