Sarbottam, mool siddhant yeh hai: nirjarā (bandhe huye karmon ka kṣaya) ke bina mukti (mokṣa) nahi milti. Aur nirjarā ka pramukh upāy tap (tapas) hai.

Tap me sabse anivārya adhyātmik/antarik rūp—dhyān hai, jo shukla-dhyān tak pahunchta hai. Mokṣa ke antim kṣaṇ me shukla‑dhyān avashyak hai; iske bina bandh karmon ka poorn kṣaya nahi hota, isliye mukti nahi milti.

Saar:

• Mool kāraṇ: Samyak‑darshan, Samyak‑jñān, Samyak‑chāritra.
• Inka pariṇām: nirjarā.
• Nirjarā ka mukhya sādhana: tap, viśeṣkar antar‑tap ka dhyān, jo shukla‑dhyān me paryavasit hota hai.
• Dono paramparā (Digambar aur Shvetāmbara) is siddhānt par ekmat hain ki mokṣa ke liye shukla‑dhyān anivārya hai.

Note: Sallekhanā (santhārā) ati‑uttam vrata mana jātā hai, parantu mokṣa ke liye avashya‑niyam nahi; avashyak hai shukla‑dhyān dwārā pūrṇa nirjarā.
