Answer

The Tattvārtha Sūtra teaches that vrata and upavāsa are important disciplines for controlling attachment, reducing karma, and progressing toward liberation.

In Jain Dharma:

• Vrata means a spiritual vow or disciplined restraint.
• Upavāsa means fasting, but spiritually it means staying close to the soul by reducing dependence on food and worldly pleasures.

Explanation

The Tattvārtha Sūtra explains vows mainly as part of right conduct.

For laypeople, it describes the twelve vows:

• Five Aṇuvratas – small vows based on non-violence, truth, non-stealing, chastity, and non-possession.
• Three Guṇavratas – vows that further limit movement, consumption, and harmful activities.
• Four Śikṣāvratas – training vows that help a householder practice more like a monk for limited periods.

Among these, fasting and deeper restraint are connected especially with practices such as:

• Sāmāyika – practicing equanimity for a fixed time.
• Proṣadhopavāsa – observing fast and spiritual discipline on special days.
• Limiting food and desires – reducing attachment to taste, comfort, and possessions.

The purpose of these vows is not merely external discipline. They help stop new karma from entering the soul and help weaken old karmas.

Spiritual Understanding

According to Jain Dharma, vows and fasting are meaningful only when practiced with:

• Ahimsa – non-violence in thought, word, and action
• Saṃyama – self-control
• Tyāga – renunciation
• Bhāva śuddhi – purity of inner intention
• Samata – equanimity

A fast without anger, pride, greed, or show becomes spiritually powerful. But fasting with ego or irritation does not bring the same inner purity.

Takeaway

The Tattvārtha Sūtra presents vrata and upavāsa as tools for self-purification. Their true purpose is not only to avoid food or follow rules, but to reduce attachment, cultivate self-control, and bring the soul closer to liberation.
