This volume is a compilation of Heindel's Mystical Interpretation of Easter and Mystical Interpretation of Christmas. The information found in these two booklets was taken from the lectures and writings of Heindel. They were intended to be an inspiration to those who have glimpsed that spark of divine light and love, and who are striving to reach that ultimate goal which was attained by Christ Jesus two thousand years ago on Golgotha. As an added bonus, we have included Heindel's Nature Spirits and Nature Forces, his mystical writings on the little understood subject of nature spirits and nature forces.
