The twelfth chapter of the Bhagavad Gita is Bhakti Yoga. In this chapter, Krishna emphasizes the superiority of Bhakti Yoga (the path of devotion) over all other types of spiritual disciplines and reveals various aspects of devotion. He further explains that the devotees who perform pure devotional service to Him, with their consciousness, merged in Him and all their actions dedicated to Him, are quickly liberated from the cycle of life and death. He also describes the various qualities of the devotees who are very dear to Him.
Arjun inquired: Between those who are steadfastly devoted to your personal form and those who worship the formless Brahman, who do you consider to be more perfect in Yog?OPEN VERSE
The Blessed Lord said: Those who fix their minds on me and always engage in my devotion with steadfast faith, I consider them to be the best yogis.OPEN VERSE
But those who worship the formless aspect of the Absolute Truth—the imperishable, the indefinable, the unmanifest, the all-pervading, the unthinkable, the unchanging, the eternal, and the immoveable—by restraining their senses and being even-minded everywhere, such persons, engaged in the welfare of all beings, also attain me.OPEN VERSE
For those whose minds are attached to the unmanifest, the path of realization is full of tribulations. Worship of the unmanifest is exceedingly difficult for embodied beings.OPEN VERSE
But those who dedicate all their actions to me, regarding me as the Supreme goal, worshiping me and meditating on me with exclusive devotion, O Parth, I swiftly deliver them from the ocean of birth and death, for their consciousness is united with me.OPEN VERSE
