Answer

In Ekasana, the main rule is to eat only once in one sitting during the day.

Regarding water, practice can vary by tradition and personal vow:

• Many Jains allow drinking boiled and properly filtered water during the permitted time.
• Some people take stricter Ekasana and drink water only during the meal.
• Some may follow an even stricter vow where water is also limited according to their Guru’s guidance.

So, you are not automatically forbidden from drinking water in Ekasana, unless your specific vow, family tradition, or Guru has instructed that.

Explanation

Ekasana means eating one time, in one place, in one sitting. The focus is on restraint, discipline, and reducing attachment to food. Water rules depend on how the vow is observed.

In Jain practice, water is generally taken with care:

• It should be boiled.
• It should be filtered.
• It should be consumed within the proper time according to your tradition.

Takeaway

If you have taken a formal Ekasana vow, follow the rule given by your Guru, temple, or family tradition. If not, drinking boiled and filtered water is commonly allowed, but with restraint and awareness.
