In plain words
As for the scriptures of the people of Bhārata, though they hold to the authority of the Vedas, the Śāstras, the Itihāsas and the Purāṇas, they have taken the Bhagavad Gītā itself as the chief authority, and today they are spreading it in the world far more widely. In matters concerning this Bhagavad Gītā we must enquire with great care, put it into right practice, and experience it in the proper way. Only when we recognise the inner meaning of each scripture and act on it can we experience at least something of the essence of this scripture too. Today people use all the authoritative scriptures merely for ritual recitations and readings; they do not recognise their inner meaning and bring about a change in their own lives. We must recognise that all the scriptures, too, teach the Supreme Principle, and are not things to be settled with a recitation. To believe that the Bhagavad Gītā belongs only to the people of Bhārata, that it is a scripture of Bhārata's own propagation and authority, is nothing but a narrow view! It is a scripture beyond place, time and person. It is a scripture beyond race, religion and caste. It is a scripture filled with the essence of Advaita. A great book filled with tattva-Jñāna. It is the essence of all the Upaniṣads, the form of all. He who has drunk this essence must become steadfast and valiant; he must not be timid and abject. But the elders, unable to recognise its inner meaning, have gone on preaching only the contents of the book, merely through propagation and preaching. These seekers are simply people caught in delusion! But the Bhagavad Gītā must make a person free of delusion. All these differences of race and religion have to do with delusions of one kind or another. The Gītā is beyond delusions. These delusions come forth only through the guṇas. God is beyond the guṇas. So, if we are to recognise divinity, if we are to reach divinity, it is most necessary to know the sacred inner meaning.
