Answer

In Jain Dharma, during Paryushan it is strongly recommended to observe brahmacharya, meaning control over sensual desires. So, if you are observing Ekashna during Paryushan, it is best to avoid sex.

Explanation

Paryushan is a sacred period for:

• self-purification
• repentance
• forgiveness
• tapasya
• control of mind, speech, and body

Ekashna means eating only once in the day as a form of tapasya. Along with food restraint, Jain practice encourages restraint in other desires too, especially sensual pleasures.

Sexual activity increases attachment, passion, and bodily indulgence, so it goes against the inner spirit of Paryushan and tapasya.

Spiritual Understanding

During Paryushan, the goal is not only to reduce food but also to reduce kashayas such as desire, attachment, and passion. Practicing brahmacharya helps the mind remain calm, pure, and focused on dharma.

Takeaway

If you are doing Ekashna in Paryushan, you should ideally avoid sex and observe brahmacharya as much as possible. This makes your tapasya more meaningful and spiritually beneficial.
