A type of Siddha (liberated soul);
that Siddha, who had attained the emancipation in the form of a hermaphrodite who was made eunuch through emasculation, and was not so by birth, for the eunuch by birth cannot become Siddha-, hence, only emaculated eunuch is relevent here (in the context of attainment of liberation).
napuṃsakalingevartamānāḥ santo ye siddhāste napuṃsakalingasiddhāḥ.
(PrasāVṛ Pa 112)
