“Value fulfillment always implies the search for excellence – not perfection, but excellence. Excellence in any given area – emotional, physical, intellectual, intuitional, scientific – is reflected in other areas, and by its mere existence serves as a model for achievement. This kind of excellence need not be structured, then, into any one aspect of life, though it may appear in any aspect, and wherever it appears it is an echo of a spiritual and biological directive, so to speak. There are different historical periods, in your terms, where the species has showed what it can do – and what is possible in certain specific directions when the genetic and reincarnational triggers are touched and opened full blast, so that certain characteristics appear in their clearest, most spectacular light, to serve as individual models and as models for the species as a whole.
"Again, such times are closely bound with reincarnational intents that direct the genetic triggering, and that meet in the culture the further stimulus that may be required. The time of the great masters in the fields of painting and sculpture is a case in point.”
