Answer

If it is 8:55 am and you want to drink water now, then:

• First, take Porsi Pachchakhān if your intention is to avoid food/drink for the next fixed period after sunrise.
• After the Porsi time is completed, you may drink water if your Pachchakhān allows it.
• For Ekasana, you take the Ekasana Pachchakhān before starting your one sitting meal, not before drinking water.

So the order is generally:

1. Porsi Pachchakhān in the morning, if you are observing Porsi.
2. Drink water only after the Porsi period is over, according to your vow.
3. Later, before your one meal, take Ekasana Pachchakhān.

What is Porsi Pachchakhān?

Porsi Pachchakhān is a Jain vow where one renounces eating, and depending on the exact vow, sometimes drinking also, for a period called Porsi.

Traditionally, one Porsi is approximately one-fourth of the daylight period, counted from sunrise. In common practice, many people understand it as roughly 3 hours after sunrise, but the exact time depends on local sunrise and daylight length.

Explanation

Ekasana means eating only once in one sitting during the day. In Ekasana:

• You eat only one time.
• You eat in one place and one sitting.
• You avoid eating again after that meal.
• Water rules may vary depending on the Pachchakhān taken and family/tradition practice.

Pachchakhān means making a clear vow of renunciation. So you should be clear whether you are taking:

• Porsi — renouncing food/water for a morning time period.
• Ekasana — limiting yourself to one sitting meal.
• Chauvihar / Tivihar — rules about food and water after certain times.

Important Note

If you already drank water before taking Porsi Pachchakhān, then you should not take it as if it had begun earlier. You can take the appropriate Pachchakhān from that point onward, according to your tradition.

For exact wording and timing, it is best to ask your local Jain guru, upāshray, or knowledgeable family elder, because Pachchakhān wording and water rules can differ by tradition.

Takeaway

Porsi is a time-based morning Pachchakhān. Ekasana is for one sitting meal. If you want water right now, first confirm whether your Porsi period is already over; then take Ekasana Pachchakhān later before your one meal.
