Book I. Sutra 43: When the object dwells in the mind, clear of memory-pictures, devoid of any form, as a pure luminous idea, this is non-distributive perception.
We are still considering external, visible objects. Such perception as is here described is of the nature of that penetrating vision whereby Newton, intending his mind on things, made his discoveries, or that whereby a really great portrait painter pierces to the soul of him whom he paints, and makes that soul live on canvas. These stages of perception are described in this way, to lead the mind up to an understanding of the piercing soul-vision of the spiritual man, the immortal.
