Srimad Bhagavad Gita -Ramanujacharya
Chapter-9 Rāja-vidyā Rāja--guhya Yogaḥ
The Regal Science & the Royal Secret
Summary of the Teaching
In the previous chapter the details about the differences among the various kinds of devotees have been dealt with. Now, after investigating the eminence of the Supreme Being who is the focus of devotion, the nature of meditation [upāsana], in the form of Loving Devotion [bhakti], is taught. The superiority of the wise [jñāni] is also elaborated upon.
This most secret knowledge — upāsana (meditation), which consists of bhakti (loving devotion). In other words — “I have told you about My pre-eminence, which is distinct from all other forms of greatness and is unlimited in its expression. You should be convinced by now of this, and so, being thus prepared, I shall now teach you that knowledge by acquiring which, and applying it, you will be freed from all things that stand in your way and prevent you from attaining Me.”
