鑠訖底 (The upper character is pronounced with the fanqie shu + zhuo; the lower character is pronounced with the fanqie ding + li. A Sanskrit word [śakti], meaning a lance here. When the sūtra mentions "holding a śakti in hand," it refers to the lance held by the Krodharāja. The lower character 底 is sometimes written in sūtras as 底 pronounced zhi, which is not the original Sanskrit sound).
