VI. Thought Forms and the Human Aura

Every sensation received from without can be observed by the one who has developed the faculty of exact spiritual perception. Persons who are greatly excited by every external impression show a continuous flickering of small bluish-red spots and flecks in the aura. In people who do not feel intensely, these flecks have an orange-yellow or even a beautiful yellow coloring. So-called absent-mindedness shows bluish flecks playing over into green and more or less changing in form.
