Newton was asked how he made his discoveries. By intending my mind on them, he replied. This steady pressure, this becoming one with what we seek to understand, whether it be atom or soul, is the one means to know. When we become a thing, we really know it, not otherwise. Therefore live the life, to know the doctrine; do the will of the Father, if you would know the Father. 41. When the perturbations of the psychic nature have all been stilled, then the consciousness, like a pure crystal, takes the colour of what it rests on, whether that be the perceiver, perceiving, or the thing perceived. This is a fuller expression of the last Sutra, and is so lucid that comment can hardly add to it. Everything is either perceiver, perceiving, or the thing perceived; or, as we might say, consciousness, force, or matter. The sage tells us that the one key will unlock the secrets of all three, the secrets of consciousness, force and matter alike. The thought is, that the cordial sympathy of a gentle heart, intuitively understanding the hearts of others, is really a manifestation of the same power as that penetrating perception whereby one divines the secrets of planetary motions or atomic structure. 42. When the consciousness, poised in perceiving, blends together the name, the object dwelt on and the idea, this is perception with exterior consideration. In the first stage of the consideration of an external object, the perceiving mind comes to it, preoccupied by the name and idea conventionally associated with that object. For example, in coming to the study of a book, we think of the author, his period, the school to which he belongs. The second stage, set forth in the next Sutra, goes directly to the spiritual meaning of the book, setting its traditional trappings aside and finding its application to our own experience and problems. The commentator takes a very simple illustration: a cow, where one considers, in the first stage, the name of the cow, the animal itself and the idea of a cow in the mind. In the second stage, one pushes these trappings aside and, entering into the inmost being of the cow, shares its consciousness, as do some of the artists who paint cows. They get at the very life of what they study and paint. 43. When the object dwells in the mind, clear of memory-pictures, uncoloured by the mind, as a pure luminous idea, this is perception without exterior or consideration. 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.
