The inward and essential part of every being is composed of fine vibrations, and the external part is formed of gross ones. The finer part we call spirit and the grosser matter, the former being less subject to change and destruction and the latter more so. ... 

The standard of right and wrong, the conception of good and evil, and the idea of sin and virtue are understood differently by the people of different races, nations, and religions; therefore it is difficult to discern the law governing these opposites. It becomes clear, however, by understanding the law of vibrations. Every thing and being on the surface of existence seem separate from one another, but in every plane beneath the surface they approach nearer to each other, and in the innermost plane they all become one. Every disturbance therefore, caused to the peace of the smallest part of existence on the surface, inwardly affects the whole. Thus any thought, speech or action that disturbs peace is wrong, evil, and a sin; if it brings about peace it is right, good, and a virtue. Life being like a dome, its nature is also dome-like. Disturbance of the slightest part of life disturbs the whole and returns as a curse upon the person who caused it; any peace produced on the surface comforts the whole, and thence returns as peace to the producer.
