Nirmal Kumar is one-man bridge between the east and the west. His writings aim at projecting that the Indian and the Western literature, philosophy, psychology and culture project the same truth in different ways. Where they differ, the differences are because they are two halves of human knowledge that have to integrate to express the truth; and that truth, too, would be only a fraction of the knowable Truth, not to mention the unknowable. He blends the Indian and Western heritage in such a way that it looks to be the development of a single mind, not two opposite currents (the twain that would meet never - Rudyard Kipling). His writings are proof that if the two currents have never met historically, they have met in his mind, and this could not have happened had they not met somewhere in God.
Times of India has written, "Nirmal Kumar has emerged as one of the greatest modern thinkers. Another popular daily Hindustan Times wries, "Nirmal Kumar draws rare psychological insights from Indian epics. They may baffle many modern psychologists who swear by Freud." The Deccan Herald daily writes, "Nirmal Kumar's argument indicates the originality of his thinking. He has the courage to think for himself" The great novelist Jainendra Kumar, wrote, "His art is like a cataract, innocent, joyous and ever-new. Nirmal is a rare boon to literature."
Regarding his poetic genius, Bachchan writes "His poetry has profound depth and power. It emanates from the sincerity with which he has looked upon nature and life."
He believes that the Indian culture is Indian by accident; in truth, it is the culture of all humanity, since it is born of the innocence and the untutored emotions of every infant heart. He calls these two channels as God's direct communication to man, without the intervention of any priest or prophet.
