Lecture I

On the other hand, the nervous system separates from the whole organism in a different way. A man who studies Theosophy in the right way will gradually notice that he perceives the difference between the four seasons of the year—the difference between summer and winter, for instance—in quite a different way than does the ordinary man of the day. The latter only feels in his own physical body, as a rule, the difference in temperature. One who has taken Theosophy into his soul in the recognised manner, not only perceives the difference in temperature, but, apart from that, he has a particular experience in his nervous system, so that, for instance, it is easier for him in summer to think certain thoughts that are connected with the physical brain than it is in winter. Not that it is impossible to think one thought or another in winter, but one can experience quite distinctly that it is easier to do so in summer; such thoughts flow more easily, as it were, in summer than in winter. We can notice that in winter it is easier to form abstract thoughts, while in summer it is easier to make them concrete and ‘picture-like.’ This is because the nervous system, the instrument for the physical plane, vibrates in a more subtle manner in harmony with the change of the seasons, and more independently of the whole organism than it otherwise does.
