The Handbook of Rising Pictures by Janet Barker
This book is intended for those engaged—or intending to be so—in Anthroposophical Medicine and/or Biodynamic Agriculture, trying to measure life force quality in plants and their products.
The Handbook should be of help to anyone interested in rising pictures, whether a layman or a scientist. It should help those interested in making rising pictures; those who do not have access to a fully equipped laboratory to standardize their methods rigorously; and those interested in how the pictures arise. The Handbook is intended to fill the void that currently exists in English as many papers on this subject are now out of print.
