Delulu in Tagore

Text from my friend Kwang: "I'm reading the home and the world... he really said delulu is the solulu". (In case you're not familiar with the phrase, here is some context.)

The novel in question is ঘরে বাইরে by Rabindranath Tagore, which Kwang was reading in translation (The Home and the World). The story is told from the perspective of the three main characters, taking turns: Bimala, Nikhil and Sandip. In the passage which Kwang was referring to – which I had forgotten, having read the novel long ago, in high school – Sandip says:

This is hypnotism indeed,—the charm which can subdue the world! No materials, no weapons,—but just the delusion of irresistible suggestion. Who says 'Truth shall Triumph'? Delusion shall win in the end.

Or in the original Bengali:

এই তো হিপনটিজ্‌ম্‌। এই শক্তিই পৃথিবী জয় করবার শক্তি। কোনো উপায় নয়, উপকরণ নয়, এই সম্মোহন। কে বলে সত্যমেব জয়তে? জয় হবে মোহের।
