Ekasana in Jainism means eating only one meal in a day, and that too in one sitting.

Simple meaning:

• “Ek” = one
• “Asana” = sitting / meal

It is a form of austerity (tap) followed by many Jain devotees, especially during vrata, pious days, or spiritual discipline. It helps in:

• reducing attachment to food,
• increasing self-control,
• supporting ahimsa, sanyam, and aparigraha.

In practice, ekasana means:

• taking food only once,
• finishing it in one sitting,
• not eating again until the next day.

In Jain tradition, this is often done with care, purity, and restraint.
