Step 1: Understanding the Concept:
Jain asceticism lists five types of conduct (Charitra) that a monk adopts as he ascends the Gunasthanas. These stages represent increasing levels of purity and the elimination of passions (Kashayas).
Step 2: Detailed Explanation:
The progressive sequence is:
1. Samayika (C): The initial state of equanimity where one vows to avoid all sins for life.
2. Chedopasthapana (E): Re-initiation into vows after a slip, or the formal shift from apprenticeship to full monkhood.
3. Pariharavishuddhi (A): A high-level conduct involving specific purification over 18 months, achieved by very few.
4. Sukshmasamparaya (B): Conduct where only a subtle trace of greed remains (at the 10th Gunasthana).
5. Yathakhyata (D): Perfect, passionless conduct as it truly should be, attained at the 11th Gunasthana and above.
The sequence is C $\rightarrow$ E $\rightarrow$ A $\rightarrow$ B $\rightarrow$ D.
Step 3: Final Answer:
The progressive order of conduct is Samayika, Chedopasthapana, Pariharavishuddhi, Sukshmasamparaya, and Yathakhyata.
