In plain words
Many dreadful deeds are done in the world; we must search out the reason why. Because selfless service has dwindled, desires that mean nothing have multiplied.
Through a coarseness that has no fear of sin, through a want of love for God, the humanity in human beings has sunk low: this is the upheaval that shakes the peace of the world.
Embodiments of Prema!
There is a Satya that time does not change, that history does not tarnish, that the deluge does not wear away and creation does not add to; the culture of Bhārata is the graceful form in which that Satya shines. The root of this culture is the Veda. What sprang from the Veda is the Upaniṣad. The essence of the Upaniṣads is the Gītā. The essence of the Gītā is the Brahma Sūtras. These three are bound to one another inseparably, each resting on the others. They go with śravaṇa, manana and nididhyāsana. The Upaniṣads are of the nature of śravaṇa. The Brahma Sūtras are of the nature of manana. The Bhagavad Gītā is of the nature of nididhyāsana. They are forms made of Jñāna alone, not forms of vāṅmaya.
But today, because the holy Prasthānatraya is regarded as vāṅmaya, man cannot move even one step forward from where he stands, though ages pass and generations change. People go into argument and counter-argument, saying that the Bhagavad Gītā is the birthright of the people of Bhārata, that it is a religious scripture, and that in the same way many books are the scriptures of the religions they arose with.
