LUCKNOW, Sept. 6 -- In times when a writer seeks a publisher even before completing a book, one written by renowned painter Prof Sukhvir Sanghal ((1914-2006), who revolutionised the wash technique of painting, five decades ago will be launched at the National Book Fair here on Sunday. Sanghal, a former principal of Lucknow University's College of Arts, is known to have Indianised the wash technique which originated in China and Japan using "Rasa" (emotions) theory. The lost manuscript is now ready for launch due to the concerted efforts of Sanghal's granddaughter Priyam Chandra. "The book "Evolution of Art and Artist" is in three volumes and the first volume will be launched on Sunday. I was assisted by former principal of Isabella Thoburn College, Anima Chakrabarti, in bringing out the book," said Chandra. "The uniqueness of the book is that it raises questions that traditional texts left unanswered. The existence of God has been interpreted through the theory of colours, the nine rasas (emotions) are explained not through the conventional derivations of Bharat, but by focusing on their psychological causes," Chandra claimed. "...Impressed by my grandfather's thoughts during a conversation, Pt Jawaharlal Nehru advised him to put his knowledge into the form of a book," Chandra claimed....
