As early as the 1940s Grad became interested in the orgone energy theories as postulated by Wilhelm Reich. The death of his daughter further stimulated his interest in spiritual healing, and in 1957 he came to know Oscar Estabany, a Hungarian refugee who professed to have healing powers. Working with Estabany in the 1960s, he carried out a series of experiments on plant seeds and mice that resulted in some of the strongest evidence of a healing power to arise in parapsychology. In a series of more complicated tests, all carried out with double blinds, Grad was able to isolate a healing power that seemed to radiate from Estabany. It could be transferred to plant seeds to stimulate their growth, to mice to speed healing, and even to water used for plants.
