Widerberg’s interests extend to primitive art and Shamanism. He practices Yoga and Subbud, a Sufi inspired form of meditation, and is well oriented in the Jewish Kabbalah tradition. He is also interested in the cosmos, theories about time and space, the possibility of life on other planets and reads science fiction books. His first lithograph on the theme of the Tarot is produced, and a series of 23 watercolours painted on the pages of books containing translated texts from alchemistic literature.
