In this book on Tiruvalluvar and Tirukkural, I have compared a lot of his couplets with the Western authors or famous persons like Einstein, Shakespeare, Voltaire, Seneca and Eastern thinkers like Adi Shankara, Buddha, Manu, Bhartruhari and Dr. Radhakrishnan. I owe a lot to SM Diaz and VR Ramachandra Dikshitar from whose brilliant works on Tirukkural, I have used quotations of great thinkers. I thank them for enlightening me and millions of Tamils.
