The largest Mahapurana, Skanda Purana of Shaiva sect in Kedara Khanda 1 says:
अष्टादशपुराणेषु दशभिर्गीयते शिवः। चतुर्भिर्भगवान् ब्रह्मा द्वाभ्यां देवी तथा हरिः॥ or ‘अठारह पुराणों में दस में शिव-स्तुति है, चार में ब्रह्मा की और दो में देवी तथा हरि की है।’
Which means out of the 18 Mahapuranas there are 10 of Shiva, 4 of Brahma, 2 of Devi and Vishnu each.
Vaishnavas and their Puranas classify 18 Mahapuranas with several dedicated to Vishnu and sometimes they do not consider Shiva Purana at all. So what are the lists of Shaivas? I heard of these:
- Shiva Rahasya
- Shiva Dharma
I also know that Dattatreya Purana is very important for some Shaivas. Can you please give some lists in Shaiva or Shakta Puranas, and by these sects?
