Step 1: Understanding the Concept:
The Vishnu Purana is often considered the model Purana because it strictly adheres to the traditional definition of what a Purana should contain. This definition is centered on the five essential subjects (Lakshanas or Upakaranas).
Step 2: Detailed Explanation:
The Vishnu Purana (3.6.25) explicitly mentions the five characteristics:
"sargaśca pratisargaśca vaṃśo manvantarāṇi ca |
vaṃśānucaritaṃ caiva purāṇaṃ pañcalakṣaṇam ||"
These five (Pancha) components are:
1. Sarga (Creation)
2. Pratisarga (Dissolution and Renewal)
3. Vamsha (Genealogies of Gods/Sages)
4. Manvantara (Ages of Manu)
5. Vamshanucharita (History of Dynasties)
While later Puranas like the Srimad Bhagavatam and the Brahmavaivarta Purana expanded this list to ten (Dashalakshana) to include topics like Vritti (sustenance), Raksha (protection), and Mukti (liberation), the Vishnu Purana remains the primary authority for the standard five-fold classification. The word "Pancha-lakshanam" itself defines the count.
Step 3: Final Answer:
According to the Vishnu Purana, there are Pancha (five) characteristics.
