In Jainism, Ekashna Pachkan (fasting for one meal a day) is a spiritual practice to purify the soul and control passions. Here is a simple guide on how to take Ekashna Pachkan properly:

1. Preparation:

- Have a peaceful mind and clear intention for fasting. - Choose one meal of the day to eat, usually the midday meal.

1. During the Fast:

- Do not eat or drink anything except the one chosen meal. - Avoid unnecessary talking and avoid harming any living beings (Ahimsa). - Engage in spiritual practices like meditation, prayer, or reading Jain scriptures.

1. Eating One Meal:

- Eat only once in the day, in moderation, without indulgence. - The meal should be simple and pure, avoiding any extravagance.

1. After the Meal:

- No more food or drink until the next day’s designated meal time. - Continue with spiritual activities and maintain control over desires.

Ekashna Pachkan helps in self-discipline and spiritual growth. Always observe it with mindfulness and respect for Jain principles.
