However, those who look only at the word-sequence of the mahAvAkyas, are likely to misunderstand them as saying : ‘The person who is in this jIva-bhava is calling himself Brahman’ - instead of correctly understanding: ‘It is Brahman that is this jIvAtmA’.
But when the mahAvakya comes forth from the mouth of the Guru it creates no such confusion. Because it says: ‘That is what you are’ and clearly implies ‘That has become you’. In fact it indicates “Without you there is nothing to be called ‘I’”. And thus modesty is automatically oozing out here.
