What is "sadaparibhuta"

Sadāparibhūta Bodhisattva, Never Disparaging Bodhisattva, (Ch: 常不輕菩薩 cháng bù qīng púsà; Jp: Jofukyo Bosatsu) appears in Lotus Sutra Chapter 20 "Never Disparaging" which describes the practices of Bodhisattva Never Disparaging, who lived in the Middle Period of the Law (Ch: 像法 xiàng fă) of the Buddha Awesome Sound King (Ch: 威音王如來 Wēi yīn wáng rúlái). He persevered in the face of persecution for the sake of the correct teaching, and finally attained Buddhahood. Bodhisattva Never Disparaging was Shakyamuni Buddha in one of his past lifetimes.
