Answer

No. In Jain Dharma, sexual activity with one’s spouse should be avoided during upvaas.

Explanation

Upvaas is not only fasting from food; it is a spiritual practice meant for:

• self-control
• purity of body, speech, and mind
• reduction of passions
• focus on dharma, prayer, reflection, and inner discipline

Sexual activity increases attachment, bodily pleasure, and passions. Therefore, during upvaas, one should observe greater restraint and avoid sensual indulgence, including sex with spouse.

Spiritual Understanding

For householders, Jain Dharma allows married life within limits, but during religious vows, tapasya, upvaas, Paryushan, Ayambil, and other spiritual observances, celibacy is considered important.

This helps the soul move away from bodily desires and toward inner purity.

Takeaway

During upvaas, it is best to observe brahmacharya and avoid sexual activity, even with one’s spouse, so the fast remains spiritually pure and meaningful.
