The Tantra ("Looms" or "Weavings"), refer to numerous and varied scriptures pertaining to any of several esoteric traditions rooted in Hindu and Buddhist philosophy. The Tantras are a total of ninety two scriptures, where sixty four are purely Ābheda, literally "without differentiation," or monistic (known as the Bhairava Tantras or Kashmir Śaivite Tantras), eighteen are Bhedabheda, literally "with differentiation and without differentiation," or monistic cum dualistic (known as the Rudra Tantras), and the final ten are completely Bheda, literally "differentiated," or dualistic, (known as the Ṣiva Tantras). The Śaiva Siddhantins use the latter two (Rudra Tantras and Ṣiva Tantras), and thus they are sometimes referred to as Śaiva Siddhanta Tantras, or Śaiva Siddhanta Āgamas.
