In plain words
In the same way, the land of Bhārata is the treasure of the sādhana for the oneness of jīva and Brahman. The land of Bhārata is a home for the pursuit of the oneness of jīva and Brahman. 'Bhārata' does not belong only to one country, or to one person, or to one time. Though many Purāṇas have proclaimed the land of Bhārata in various ways, we may say they tell only their own several fancies.
The word Bharata:
Because Jaḍa Bharata ruled the land of Bhārata, this … land came to be called Bhārata. It may be said that because Bharata, the son of Śakuntalā and Duṣyanta, ruled this land, this land came to be called Bhārata. The Purāṇas may say that because Bharata, the brother of Śrī Rāmacandra, crowned 'Rāma's sandals' alone and ruled with a pure heart, the name 'Bharata' came to this land. Now, when was this word Bharata born? Surely only because the name Bharata was there even before Jaḍa Bharata. They called this Jaḍa Bharata by the name Bharata. Surely only because this name 'Bharata' was there before the son of Śakuntalā and Duṣyanta! They gave it to their son as his name.
In just the same way, the name Bharata has been there from time without beginning. Sarvasvati, Bhagavatī, Bhāratī: these names of Sarasvatī are full of meaning. Since Sarasvatī is the embodiment of the goddess of speech, every man who comes forth through speech is truly a Bharata. It is not a name that belongs only to this country, only to this time. This word 'Bharata' applies to the whole human race. 'Bha' means the syllable bha, which stands for the principle that is divine Jñāna itself. The Jñāna of one's own true nature, that alone is bha. One who delights in this bha is a Bharata. One who makes the self-luminous Jñāna manifest is a Bharata. 'Saṅgramaṃ tanotīti bharataḥ': that is the source of the word. That is, it means that one skilled in battle is a Bhāratīya. What is battle? Meeting the power of the demonic nature with the power of the Ātma. So every man who meets the power of the demonic nature within him with the divine and glorious power of the Ātma is a Bhāratīya. Balam, bharam, bhavati, bibhartiḥ are the words of the derivation; balam means brahma-balam; tejo-balam, kṣātra-balam. One endowed with these three forms is a Bharata. In the Śruti, one meaning of balam is yajña. 'Yajñaṃ ātmabalaṃ vā tanotīti bhārataḥ': that is, one who has gained the power of the Ātma through yajña is a Bhāratīya. Ātma-balam means: the one who gains the power of God is a Bhāratīya.
