In Jainism, "upsarg" refers to obstacles, troubles, or persecution faced by spiritually advanced souls, especially Jain munis (monks) and Tirthankaras, due to their practice of austerity, truth, and non-violence. These upsargs are often caused by envious or ignorant beings, both human and celestial, who become disturbed by the monk's spiritual progress.
