• Vachana (वाचन): svādhyāya ke pehle charan ki kriya. Isme shastra-padh, śravan (sunna) ya padh kar dharm ki baaton ko samajhna hota hai. Seedha arth: scriptures ko padhna/sun-na aur samajhna.

• Amnaya (आम्नाय): svādhyāya ke aakhri vai charan ki kriya. Isme jo padh kar samjha, use yaad rakhna, baar-baar repeat karna, aur manan-dharana ke through dharm ko antar-ātmā me sthapit karna shamil hai. Seedha arth: recitation/memorization and firming the teaching in memory.

• Digambar vs. Shwetambar: dono sampradayo me in stages ki samajh aur prayog ek saman hai. Core idea yehi hai ki pehle shastra ki sunvai/padhai (vachana) ho, phir usko yaad rakhna aur manan karna (amnaya) kiya jata hai. Khaas fark ke roop me in ki murtibhed ke daayre me zyada antar nahi hota; dono ki dharma-shiksha me svādhyāya ke yeh char aadhaar ke roop me maane jate hain.

If you want, I can explain these stages with specific Jain sutras or verses as per Digambar or Śvetāmbara references.
