From a clear knowledge of the Bhagavad-gita all the goals of human existence become fulfilled. Bhagavad-gita is the manifest quintessence of all the teachings of the Vedic scriptures.
All the manifested world of things and beings are projected by imagination upon the substratum which is the Eternal All-pervading Vishnu, whose nature is Existence-Intelligence; just as the different ornaments are all made out of the same gold.
Loud speech, profusion of words, and possessing skillfulness in expounding scriptures are merely for the enjoyment of the learned. They do not lead to liberation.
Do not be proud of wealth, people, relations and friends, or youth. All these are snatched by time in the blink of an eye. Giving up this illusory world, know and attain the Supreme.
