Naru embarked on a lifelong cerebral journey to find answers to a few questions that had appeared in his mind very early in his life. It was only in his mid-forties that he got the chance to start organising the thoughts and experiences that he had gathered thus far. A little before that time, he came into contact with the 'Wisp’. That chance encounter had a big impact on the progress of his search. Without being present in tangible format in his world, ‘Wisp’ guided Naru’s quest in an enigmatic way for a long time. Naru crossed one hurdle after another to arrive at his own explanations of the concepts of Bangla, the origin of the term ‘Bangal’, the naming of ‘Banga’, etc. He thought that his journey was over and that he had been able to achieve what he intended to. That’s when he felt the presence of a spectre in the past of the Bengal Basin. His search convinced him that all the travellers in history who dealt with the Bengal Basin felt its presence. Like all the previous travellers, he also lost his way to reach that phase of Bengal’s history that precedes the presence of the spectre. There was a void.
He called the simulated form of his ‘Wisp’ that he had successfully created in his mind to make up the emptiness that the absence of the ‘Wisp’ caused. The direction from the ‘Wisp’ was not sufficient to breach the barrier posed by the void. He took the virtual ‘Wisp’ to the place where they first met a long time ago. This time he tried to use the ‘Wisp’ as an instrument of his journey instead of an enigmatic direction giver. He achieved success in his effort. ‘Wisp’ broke the barrier posed by the void and took Naru to the other side of that barrier.
The new light that illuminated the distant horizon of the history of the Bengal Basin had the capability to solve a great number of mysteries that are associated with that basin.
