Answer

Yes, generally you may take sugarcane juice in the afternoon on the day after doing parna for 8 upwas, provided:

• Your digestion is comfortable.
• You have already done proper parna in the prescribed way.
• The juice is fresh, clean, and taken before sunset.
• It does not go against any niyam or guidance given by your Guru Maharaj Saheb/Sadhviji.

Explanation

After 8 upwas, the body’s digestive strength is usually weak. So even after parna, one should take food and drinks slowly and carefully.

Sugarcane juice can be heavy and very sweet for some people. If taken in excess, it may cause acidity, heaviness, loose motions, or discomfort. So if you take it, take a small quantity first.

It is better if the juice is:

• Freshly extracted
• Not stored for long
• Without ice
• Without lemon, ginger, black salt, or other additions if you are following strict Jain food discipline

Spiritual Understanding

In Jain Dharma, after tapasya, parna should be done with awareness, gratitude, and self-control. The purpose is not to immediately satisfy taste, but to restore the body gently while maintaining the bhav of tapasya.

Takeaway

You can take sugarcane juice in the afternoon after 8 upwas parna day, but take it fresh, in small quantity, before sunset, and only if your body feels ready. If you have taken any specific niyam, follow your Guru’s guidance first.
