Short answer in Jain Dharma:

• Tirthankar aate hain devlok (divine realms) se pratyaksh roop se dharma ki shiksha dene ke liye, fir prithvi par avataar lete hain. Isliye kahin “devlok se aaye” ki baat sahi hai: ve apne upari sthan se aakar dharma ki prachar karte hain.

• Chaubisi (चारबीसी/chaubisi) ya “24 Tirthankaraon ki ek chakracal” ke hisaab se har avasarpini ke ant me 24 Tirthankara hote hain. Humari current half-cycle (avasarpini) me 24th Tirthankara Mahavira the; unke baad is half-cycle me aur Tirthankar nahi hote. Isliye agle chaubisi me naye 24 Tirthankara aayenge, lekin wahi cycle dobara shuru hone par hoga, jab kalp ki dhaara dobara chalti hai.

• Digambar aur Shwetambar traditions me kuch Tirthankaron ki suchi par thodi-modi sa teeke (naam, sthiti) ki bhinnata mil sakti hai, par mool tattva yehi hai: har half-cycle me 24 Tirthankara aate hain, aur Mahavira is cycle ke antim Tirthankar hain.

Agar aap chahen to main spast roop se Digambar aur Shwetambar ki suchiyon ki bhinnata aur unke arth (arth) bhi saaf tor par samjha sakta hoon.
