分段生身名為虫身，身有虫故。《大般若》三百二十六、四百四十八云：「善現！不退菩薩身心清淨，非如常人身中恒為八萬戶虫之所侵食。所以者何？是諸菩薩善根增上出過世間，所受身形內外清淨，故無虫類侵食其身。如如善根漸漸增益，如是如是身心轉淨，由此因緣是諸菩薩身心堅固猶若金剛，不為違緣之所侵惱。」

The physical body of fragmented birth is called a "worm-ridden body" because there are worms in the body. The Mahāprajñāpāramitā-sūtra, fascicles 326 and 448, states: "Subhūti! The body and mind of a non-retrogressing bodhisattva are pure, not like those of ordinary persons whose bodies are constantly invaded and devoured by eighty thousand families of worms. Why is this? These bodhisattvas have superior roots of goodness that surpass the world; the bodily forms they assume are pure inside and out, and therefore no classes of worms invade and devour their bodies. Just as their roots of goodness gradually increase, so too their body and mind become increasingly pure; due to this condition, the bodies and minds of these bodhisattvas are solid like vajra and are not plagued or tormented by adverse conditions."
