Important Verse of Srimad Bhagvadgita-11

In this world, there is nothing so sublime and pure as transcendental knowledge. Such knowledge is the mature fruit of all mysticism. And one who has achieved this enjoys the self within himself in due course of time....4:38


In this world nothing is as purifying as spiritual knowledge. Then why is not everyone pursuing this? Lord Krishna explains that first one must become qualified from prolonged practice of karma yoga or prescribed Vedic activities performed without desire for rewards. Then in due course of time if there is no interruption knowledge will arise leading to purity of heart after which atma tattva or soul realisation will be achieved.
And this knowledge is hidden like smoke in firewood,oil in the oil seeds and butter in the milk...there is nothing from outside to achieve the same jiva (individual consciousness) would turn into super consciousness one it is churned by suffering. All our accumulated actions ( sanchita karma) would also be wiped out from us , we wont be operation by conditioning of mind or the perception of past accumulated experiences nor we do the judgement based on the experiences accumulated as memory , The mind actions would be pure as it is..
