Lamps of Knowledge
Lamps at the Altar represent the "light" that Knowledge creates since it is the Knowledge that we utilize in our everyday lives that gives our lives meaning. When we understand The Way, we may understand the true nature of the world today.
Without Knowledge to guide Individuals on their paths, Individuals would be trapped within their own perpetual cycles of Suffering; The basis of Samsara.
The Lamps at the Altar represents the Illuminated Way, that Knowledge provides.
