In Jainism, "ekasana" refers to a specific practice of limiting food intake as a form of discipline and spiritual observance. "Bhagwan na ekasana" generally means performing ekasana in honor or remembrance of the Tirthankaras (revered spiritual teachers, often referred to as "Bhagwan" in Jain tradition).

What is Ekasana? Ekasana literally means "one sitting" (eka = one, asana = sitting/meal). In this practice, a person eats only once during the day, usually before sunset, and refrains from consuming any food (and sometimes water, depending on the vow) for the rest of the day. This is done mindfully, with the intention of reducing attachment to food and practicing self-control.

Purpose:

• It is a form of tapasya (austerity) and anuvrat (small vow) aimed at purifying the soul, reducing karma, and fostering detachment.
• Doing ekasana "for the Bhagwan" means dedicating the merit of this austerity to the Tirthankaras, as an act of devotion or in their remembrance.

When is it practiced?

• Ekasana may be practiced on special Jain religious days (like Paryushana, Aayambil Oli, Mahavir Jayanti), during personal vows, or as part of one's daily spiritual routine.
• Some Jains choose to do ekasana regularly, while others may do so only on certain auspicious days or as an act of penance.

How is it performed?

1. The practitioner eats only one meal during the day.
2. The meal is taken at one sitting, without getting up or changing place.
3. After the meal, no further food (and sometimes water) is consumed until the next sunrise or next permitted meal time.
4. The meal is taken with mindfulness, often preceded by prayers or reflection on the Tirthankaras.

Spiritual significance:

• Fosters discipline and detachment (vairagya).
• Helps in controlling desires and passions.
• Accumulates punya (spiritual merit).
• Remembrance of the Bhagwan and their teachings.

This practice is a common way for lay Jains (shravaks and shravikas) to engage in self-discipline and devotion as taught in Jain philosophy.
