Here’s a simple, traditional way to take pachkhan (paccakkhāṇa) to renounce root vegetables (kandamūl). Keep it sincere and time-bound.

What pachkhan is

• Pachkhan means a formal resolve/renunciation you accept before the Jinas, your Guru, or sacred scriptures.
• It is usually taken in the morning, or before meals, and can be for a day, a festival period (e.g., Paryushan), Chaturmās, or lifelong.

How to take it (step-by-step) 1) Prepare

• Bathe if possible, wear clean clothes, and choose a quiet place.
• Sit or stand facing the Jina idol or sacred texts, or before your Guru if present.

2) Bow

• Recite the Navkar Mantra 3 or 9 times with folded hands.

3) State your resolve clearly (name, dates, what you are renouncing)

• Say it aloud, slowly and sincerely.
• Include the start date and end date (or say “lifelong”).

4) Close with repentance

• End with “Micchāmi Dukkaḍaṁ,” asking forgiveness for past, present, or future lapses.

Suggested wording you can use

English “I, [full name], today on [date], accept a firm resolve to renounce all root vegetables (kandamūl) such as potato, onion, garlic, ginger, turmeric root, carrot, beet, radish, yam, etc., from now until [end date]/lifelong, for the purity of food and to minimize himsā. If I transgress knowingly or unknowingly, I will do ālochana–pratikraman and accept prāyaścitta. Micchāmi Dukkaḍaṁ.”

Hindi “मैं, [पूरा नाम], आज [तारीख] से [अंतिम तारीख]/जीवनभर तक, कंद-मूल (आलू, प्याज़, लहसुन, अदरक, हल्दी की गांठ, गाजर, चुकंदर, मूली, रताळू आदि) का त्याग करता/करती हूँ। यदि जान-बूझकर या अनजाने में अपराध हो जाए, तो मैं आलोचना–प्रतिक्रमण और प्रायश्चित्त करूँगा/करूँगी। मिच्छामि दुक्कडम्।”

Śvetāmbara traditional line you may add “Kevali-pannatti paḍiṭṭhiyaṁ, ajja me [tārīkhe]e kandamūla-tyāga-paccakkhāṇaṁ.” Then: “Micchāmi Dukkaḍaṁ.”

Digambara traditional line you may add “Ajja mi [nāma] [tāriḵha]e kandamūla-tyāga-vrataṁ dhārema/paḍihāraemi; savvado na karemi. Micchāmi Dukkaḍaṁ.”

Aftercare and lapses

• If you slip (e.g., eat a root by mistake), do immediate ālochana (confession) before the Jina/Guru, recite Navkar Mantra, say what happened, accept a small prāyaścitta (e.g., extra Navkar, sviādhyāy, or a meal restraint), and re-take the same pachkhan for the remaining period.

Notes by tradition

• Śvetāmbara and Digambara both uphold avoiding root vegetables to reduce countless one-sensed lives destroyed in uprooting. Wording varies slightly; the intent is identical: non-violence and food purity.
• If a Guru or learned elder is available, take pachkhan in their presence. If not, taking it before the Jina idol or scripture is acceptable.

Keep it simple, truthful, and time-bound. May this resolve support ahimsā and inner purity. Micchāmi Dukkaḍaṁ.
