Siddhachakra (or Sidhchakra) is mainly connected with the famous Jain story of King Shripal and Queen Mayanasundari. This katha is very popular in the Śvetāmbara tradition and is closely linked with Ayambil Oli and Siddhachakra Pujan.

Here is the story in simple form:

1. King Shripal’s background

- Shripal was a brave but unlucky king (or prince, in some narrations). - Due to past karmas, he suffered from kushta rog (leprosy-like disease) and lost his kingdom. - People avoided him, and he faced a lot of pain and insult.

1. Princess Mayanasundari’s vow

- In another city lived Princess Mayanasundari, a devout Jain. - Her parents wanted to marry her to a handsome, healthy prince. - But Mayanasundari had taken a vow: - “I will marry only the person to whom my guru (sadhu) gives me in charity (daan).” - One day, a Jain sadhu came for gochari to her house. - The king (her father), in devotion, said: - “Maharaj, please ask for anything – even my daughter – I will give.” - The sadhu, seeing from keval-darshan/avadhi‑jnan type divine insight (as per katha) the future of Shripal and Mayana, said: - “Give your daughter in daan to that diseased man (Shripal) sitting outside.” - Everyone was shocked, but Mayanasundari happily accepted, thinking: - “This is guru’s aagna and my own vow.”

1. Married life in suffering

- Shripal and Mayanasundari started living a very simple, difficult life. - They had no wealth, Shripal was diseased, and they wandered from place to place. - Still, Mayanasundari never complained. She served her husband and kept strong faith in Jain dharma and guru‑aagna.

1. Guidance of the Sadhu and Siddhachakra Aradhana

- Once they met the same Jain sadhu again. - Seeing their faith and suffering, the sadhu taught them the aradhana of Siddhachakra / Navapad and the Ayambil Oli vrat: - Worship of Navapad (nine supremacies): 1. Arihant 2. Siddha 3. Acharya 4. Upadhyaya 5. Sadhu 6. Samyak Darshan 7. Samyak Jnan 8. Samyak Charitra 9. Tap - Perform Ayambil (one-sitting, tasteless simple food, no spices etc.) for 9 days with bhakti. - Do Siddhachakra Pujan / Vidhan with full shraddha, contemplating the Navapad.

1. Miracle of faith and puja

- Shripal and Mayanasundari did Navpad / Siddhachakra aradhana exactly as instructed. - Due to the strength of punya, tapasya and pure bhav: - Shripal’s disease was cured. - They regained health, respect, and later kingdom and great prosperity. - The story shows that Shripal became a powerful and successful king again, and Mayanasundari was greatly honored.

1. Spiritual message of the story

- The real “miracle” is not worldly success, but: - Firm guru‑aagna palan (following the guru’s order). - Unshakable samyak darshan and trust in Navakar / Navapad. - Power of Ayambil Oli and Siddhachakra Pujan done with pure heart. - The story teaches: - Even the hardest karmas (like disease, poverty, insult) can become light when we do right faith, right knowledge, right conduct, and tapa. - Devi‑devta etc. are not the main cause; the main cause is our own shuddha bhav and Navapad aradhana.

1. Relation with Siddhachakra Yantra

- From this katha, the Siddhachakra yantra and its puja became very famous. - The yantra shows in symbolic form: - Panch Parmesthi + Ratnatraya + Tap = Navapad - Worship of this yantra reminds us: - “My real goal is to become like the Siddhas by following this path.”

1. Śvetāmbara – Digambara note

- Śvetāmbara tradition: - Gives strong emphasis to Shripal–Mayanasundari katha, Siddhachakra Pujan, Ayambil Oli with this story. - Siddhachakra mandal / yantra is widely used in vidhans. - Digambara tradition: - Navapad aradhana and Navakar mantra are equally respected, but - This specific Shripal–Mayanasundari linked Siddhachakra Pujan is less central; style of worship and stories differ. - In both, the essence is same: deepest respect to Panch Parmesthi and Navapad.
