Fix the mind in Me (the Supreme), be My devotee, offer everything to Me, pay obeisance to Me. By dint of the resultant integration, making Me as the sole refuge, you will attain Me.
Krishna has explained conclusively how the Supreme is the sole source, sustenance and refuge of the whole world, and all that it has evolved and is preserving. He also showed how Vedic injunctions only bring a fate of going up and coming down repeatedly.
Manifold ritualistic means are short-sighted, and bring downfall. The right course is to turn away from everything else, and fix the mind fully on the Supreme.
Such exclusiveness alone will lift the devotee safely to be one with the Supreme. In thoughts, words, deeds, dedication and goal, one should have only the Supreme – Its “supreme-ness”. Then that will make him one with the Supreme, not to be separated any more.
This is the last note of fullness, abundance, the ecstasy of freedom and oneness! The last note of genuine human fulfilment!
