Lecture II
In this case we first start with man in the world of sense, living in the physical world. At first he lives his physical existence in such a way that he realises his surroundings by means of his senses; and through his organs of touch, by means of his hands and feet, by handling, walking, speaking, he reacts on the physical world around him. Man realises the surrounding world by means of his senses and he works upon it, in a physical sense, by means of his organs of touch. Sankhya philosophy is quite in accordance with this. But how does a man realise the surrounding world by means of his senses? Well, with our eyes we see the light and colour, light and dark, we see, too, the shapes of things; with our ears we perceive sounds; with our organ of smell we sense perfumes; with our organs of taste we receive taste-impressions. Each separate sense is a means of realising a particular part of the external world. The organs of sight perceive colours and light; those of hearing, sounds, and so on. We are, as it were, connected with the surrounding world through these doors of our being which we call senses; through them we open ourselves to the surrounding world; but through each separate sense we approach a particular province of that world. Now even our ordinary language shows us that within us we carry something like a principle which holds together these different provinces to which our senses incline. For instance, we talk of warm and cold colours, although we know that this is only a manner of speaking, and that in reality we realise cold and warmth through the organs of touch, and colours, light and darkness through the organs of sight. Thus we speak of warm and cold colours, that is to say, from a certain inner relationship which we feel, we apply what is perceived by the one sense to the others. We express ourselves thus, because in our inner being there is a certain intermingling between what we perceive through our sight and that which we realise as a sense of warmth—more delicately sensitive people, on hearing certain sounds can inwardly realise certain ideas of colour; they can speak of certain notes as representing red, and others blue. Within us, therefore, dwells something which holds the separate senses together, and makes out of the separate sense-fields something complete for the soul. If we are sensitive, we can go yet further. There are people, for instance, who feel, on entering one town, that it gives an impression of yellow another town gives an impression of red, another of white, another of blue. A great deal of that which impresses us inwardly is transformed into a perception of colour; we unite the separate sense-impressions inwardly into one collective sense which does not belong to the department of any one sense alone, but lives in our inner being and fills us with a sense of undividedness whenever we make use of any one sense-impression. We may call this the inner sense; and we may all the more call it so, inasmuch as all that we otherwise experience inwardly as sorrow and joy, emotions and affections, we unite again with that which this inner sense gives us. Certain emotions we may describe as dark and cold, others as warm and full of light. We can therefore say that our inner being reacts again upon what forms the inner sense. Therefore, as opposed to the several senses which we direct to the different provinces of the external world, we can speak of one which fills the soul; one, of which we know that it is not connected with any single sense-organ, but takes our whole being as its instrument. To describe this inner sense as Manas would be quite in harmony with Sankhya philosophy, for, according to this, that which forms this inner sense into substance develops, as a later production of form, out of Ahamkara. We may, therefore, say: First came the primeval flood, then Budhi, then Ahamkara, then Manas, which latter we find within us as our inner sense. If we wish to observe this inner sense, we can do so by taking the separate senses and observing how we can form a concept by the way in which the perceptions of the separate senses are united in the inner sense.
