Step 1: Puranic Classification.
The Puranas are categorized into three groups based on their emphasized gunas (qualities):
- Sattvika Puranas (emphasizing devotion to Vishnu)
- Rajasika Puranas (emphasizing devotion to Brahma)
- Tamasika Puranas (emphasizing devotion to Shiva and associated deities)
Step 2: Sattvika Purana Examples.
Vishnupurana, Bhagavata Purana, Naradeya Purana, and Padma Purana are examples of Sattvika Puranas. They focus on glorifying Lord Vishnu and promoting sattva guna (purity and balance).
Step 3: Shivapuranam's Category.
Dedicated to Lord Shiva, the Shivapuranam falls under the Tamasika category. Consequently, it is not classified as a Sattvika Purana.
Step 4: Final Determination.
Based on these classifications, the Shivapuranam is identified as the Purana that is not Sattvika among the provided options.
