In plain words
One who has thus beheld the principle of the Ātma within all beings never reviles other religions. He sets no foot in religious quarrels. He does not ridicule other faiths. He raises no obstacle to the beliefs of others. Denouncing others' beliefs as false, fomenting religious quarrels, ridiculing each other's modes of worship, muttering that they are 'superstitions' — such ill intentions, and others like them, are simply the naive and the ignorant, without experience of their own; they are unfitting for mere human beings. Whoever's beliefs give them bliss — those beliefs bestow bliss. 'Ekaṃ Sat Viprāḥ Bahudhā Vadanti' — one and the same substance, each person beholds and describes in his own way. No one at all can deny this, and no one at all has any authority to do so.
Only those who seek to attain equanimity are those who do not strive to harm others. For one who harms others, the word 'Hindu' is not fitting. To hold the principle of the Ātma as one, joining hearts together in embrace with Prema — this alone is the highest teaching of Bharatiyas. Those who possess such equanimity — whatever language they speak — bear self-confidence as their mark; this alone is the chief mark of a Bharatiya. All such people are the close kin of Bharatiyas.
Man is a mere mass of physical substance — proclaiming this while, for their own advancement, having taken the non-Ātma doctrine alone as their basis — those who have remained so
