Shailendra’s Unique Composition- Is it the 9th Alankar, “Shailendralankar” ?

Shailendraji wrote the song “Din Dhal Jaaye Haaye Raat Na Jaaye… Tu To Na Aaye, Teri Yaad Sataaye”. Whether by Design or by Default, He Created something Unique in this song which, to the best of my knowledge, has not been pointed out till now. In the world of Hindi Grammar, it may be something to include as an Example in Hindi grammar Books. Had I had A million Rupees to Offer as a Prize Money to the person who would Point It out, I would have Happily done that. Alas I don’t have that kind of Money.
