The Bhagavad-Gita is not seperate from the Vaishnava philosophy and the Srimad Bhagavatam fully reveals the true import of this doctrine which is transmigration of the soul. On perusal of the first chapter of Bhagavad-Gita one may think that they are advised to engage in warfare. When the second chapter has been read it can be clearly understood that knowledge and the soul is the ultimate goal to be attained. On studying the third chapter it is apparent that acts of righteousness are also of high priority. If we continue and patiently take the time to complete the Bhagavad-Gita and try to ascertain the truth of its closing chapter we can see that the ultimate conclusion is to relinquish all the conceptualized ideas of religion which we possess and fully surrender directly unto the Supreme Lord."

The idea that man is like unto an inverted tree seems to have been current in by gone ages. The link with Vedic conceptions is provided by Plato in his Timaeus in which it states... behold we are not an earthly but a heavenly plant."
—Henry David Thoreau
I owed a magnificent day to the Bhagavad-Gita. It was the first of books; it was as if an empire spoke to us, nothing small or unworthy, but large, serene, consistent, the voice of an old intelligence which in another age and climate had pondered and thus disposed of the same questions which exercise us.
—Ralph Waldo Emerson
