“Each of these private teachers who work for pay … inculcates nothing else than these opinions of the multitude which they opine when they are assembled and calls this knowledge wisdom.”

The Notebooks of Leonardo da Vinci (1883), II Linear Perspective
Context: Drawing is based upon perspective, which is nothing else than a thorough knowledge of the function of the eye. And this function simply consists in receiving in a pyramid the forms and colours of all the objects placed before it. I say in a pyramid, because there is no object so small that it will not be larger than the spot where these pyramids are received into the eye. Therefore, if you extend the lines from the edges of each body as they converge you will bring them to a single point, and necessarily the said lines must form a pyramid.

Alternative translation: "Lord Rama was an incarnation of God who possessed 14 types of divine power. Lord Krishna was an incarnation of God who possessed 26 types of divine power. But I am fully perfect and the master of all the 64 divine powers."
This alternative translation, very different from the original Hindi, appeared in a book named Satgurudev (1970). It has been used by several scholars (Messer, Glock and Bellah; Reender Kranenborg) to position Hans Ji Maharaj as claiming to be more powerful than Krishna.
