This recent translation of a masterwork of esotericism 
places humankind at the very heart of the 

vast, invisible processes of cosmic evolution. When we use the term natural
science don't we mean that we are dealing with knowledge of nature?

Esoteric science is the science of what takes place esoterically, in the sense
that it is perceived not outside in nature but where one's soul turns when it
directs its inner being toward the spirit.

Esoteric science is the opposite and counterpart of natural science. —Rudolf Steiner

As vital and relevant as when it was first published in 1910, this masterpiece
of esoteric, Rudolf Steiner worked and reworked on rosicrucian cosmology for
many years to make it increasingly precise and accurate. This work remains
the most effective presentation to date of a spiritual alternative to contemporary
materialist cosmologies and the Darwinian view of human nature and evolution.
In this basic work of spiritual science, readers learn how the creation and
evolution of humanity is embedded at the heart of the vast, invisible web of
interacting cosmic beings, through whom the alchemical processes of cosmic
evolution unfold. There are also descriptions of the various bodies of the human
being, their relationship to sleep and death, and a detailed, practical guide to the
methods or exercises, including the Rose Cross Meditation," through which such
initiation knowledge can be attained. Most remarkable and revolutionary of all,
perhaps, is the central function that Rudolf Steiner allots to the Christ and to the
entrance of Christ into earthly evolution through the Mystery of Golgotha.
