For a musician, visualization is the process of picturing in our minds — Visualization

"Imagery played a central role in theories of the mind for centuries. For example, the British Associationists conceptualizes thought itself as sequences of images. And, Wilhelm Wundt, the founder of scientific psychology, emphasized the analysis of images. However, the central role of imagery in theories of mental activity was undermined when Kulpe, in 1904, pointed out that some thoughts are not accompanied by imagery (e.g., one is not aware of the processes that allow one to decide which of two objects is heavier)."

"The medium of printed scientific text is first of all a visual one."

"Within the atom occur phenomena concerning which visualization is futile, to which common sense, the guidance from our everyday experience, has no application, which yield to studies by equations that have no meaning except that they work."

"Visualization is simply the creation of a strong mental image of the thing desired, the perfecting it each day until it becomes almost as clear as an existing material thing."

"If statistical graphics, although born just yesterday, extends its reach every day, it is because it replaces long tables of numbers and it allows one not only to embrace at glance the series of phenomena, but also to signal the correspondences or anomalies, to find the causes, to identify the laws."

"While the film Life of Christ was rolling past before my eyes I was mentally visualizing the gods, Shri Krishna, Shri Ramachandra their Gokul and Ayodhya.. I was gripped by a strange spell. I bought another ticket and saw the film again. This time I felt my imagination taking shape in the screen. Could this really happen? Could we the sons of India, ever be able to see Indian images on the screen. The whole night passed in this mental agony."
