Despite his fame, Drtikol, a devout Buddhist, continually sought to express his quest for the divine. This need intensified in 1929 when, on Wenceslas Square, as he told a student, he attained nirvana. His work became more abstract – and erotic. His famous, Matka země (Earth Mother, 1931), a nude woman with the silhouettes of a man and a woman poised in front of her groin, comes from this period.
