Navpadji (Siddhachakra/Navapad) sabse pramukh yantra hai. Iske “jaise aur kitne tantra/yantra” ka koi ek nishchit aagamik ank nahi hai. Paramparā ke anusar ginti badalti hai.

• Shwetambar paramparā: Siddhachakra ke saath alag‑alag yantra‑pujā ki paramparā milti hai. Kuchh sthalo/parivāro meṁ “30 Yantra” ki paramparā chalti hai; kai jagah “99 (Navāṇu) Yantra” ka upyog hotā hai. Iske atirikt Panch‑Parmeṣṭhī Yantra, 24 Tirthankar‑yantra, Parshvanath ke 108/1008 yantra, Chakreshvarī, Padmāvatī, Ashtamaṅgalā, Jina‑Vāṇī, Chaturvidh‑Dān ādi bhi prayukt hote hain.
• Digambar paramparā: Yantra‑ginti ka koi ek adhikrut suchi nirdharit nahi milti. Yahan stotra‑sādhana (jaise Bhaktāmbar, Kṣemapana, etc.) mukhya hai; kuchh sampradāyoṁ meṁ kuchh yantra‑upayog mil jātā hai, par ek sārbhaumik “kitne” ka niyamakankh nahi.

Isliye saral uttar: Navpadji ke alāvā kai yantra paramparāon meṁ milte hain, par unki kul saṅkhyā ek si nahi hoti; sthān, gachchh/sangh aur parivār‑paramparā ke anusar badal jati hai.
