Profound words indeed. Although he referred to his Dadi, he will soon realise that these very same words are meant for the woman who stood in front of him, so full of love, admiration, respect and relief in her eyes. She will soon become his everything just as he will become hers.
I must say that I have never witnessed a more unique way of portraying the realisation of love between the main protagonists. Although they did not say the words out loud, their eyes spoke volumes. Love is not just romance for these two, it is a spiritual experience for them.
