Are there specific rules or preparations required before performing Shradh at Prayagraj?

Yes, similar rules apply here to maintain sanctity:

• Purification: Take a bath, preferably the holy dip (Snan) at the Triveni Sangam, before the ritual. Wear clean, simple attire (dhoti/kurta for men, simple saree/suit for women).
• Diet: Follow a Sattvic (pure vegetarian) diet, avoiding onion, garlic, meat, eggs, and alcohol, especially on the day of Shradh. Fasting until the completion of the ritual is common.
• Conduct: Approach the Sangam with utmost reverence. Maintain a calm, devotional state of mind.
• Abstinence: Avoid shaving, haircuts, and cutting nails during Pitru Paksha or on the day of the Shradh before the ritual is completed.
