Irene,
==> Is anyone aware of material on Kāpālikas that's not in English? <==
Apparently not.
Although no written works by Kāpālikas are known to us, this antinomian Śaiva movement of
skull-bearers, who took up the attributes of Śiva’s frightening form,
Bhairava, was once very
much present from Kashmir and Nepal to the Tamil-speaking South.
The earliest mention of
Kāpālikas is found perhaps in Hāla’s Saṭṭasaī, datable in the 3rd to 5th centuries CE (Lorenzen,
1991, 13), but most of our sources on them come from the 7th to the 12th centuries CE.
Since
we have mainly indirect sources about their doctrine and practice, it is often difficult to separate
fictitious or biased elements from what may be true in their descriptions.
