Shaiva practice is weighted toward tapas — heat, austerity, the discipline that burns through obstruction. Its extreme forms produced the sadhus and the Aghori, whose deliberate transgressions (cremation-ground residence, ritual use of the taboo) are a theology: if Shiva is everywhere, then nothing can be inherently polluting. Most Shaivas practice nothing of the kind, but the tradition's tolerance for that pole is part of what it is.
