Answer

In Jain usage, ekavtaari jiva generally means a soul that has only one more birth left before liberation. It does not have a fixed outer mark or physical sign. Its real signs are mainly inner spiritual qualities. ( dadashri.org)

Explanation

The characteristics usually associated with such a soul are:

• Right faith (samyagdarshan / samyaktva)
• Inner calmness or spiritual peace
• Strong desire for moksha
• Detachment from worldly pleasures
• Compassion toward all living beings
• Firm trust in Jain tattvas and the path of liberation
• Very mild passions like anger, pride, deceit, and greed
• A natural tendency toward restraint, vows, and self-discipline ( jainworld.jainworld.com)

Spiritual Understanding

In Jain Dharma, such a state is understood through the signs of samyaktva. The scriptures describe qualities like praśama (calmness), saṃvega (urge for liberation), nirveda (detachment), anukampā (compassion), and āstikya (firm faith in Jain truth). These are the real indicators of spiritual progress, not external appearance. ( wisdomlib.org)

Takeaway

So, an ekavtaari jiva is usually recognized by deep right faith, detachment, compassion, and a strong pull toward liberation. Ordinary people cannot definitively पहचान such a soul by sight alone; its true status is subtle and inward. ( jainworld.jainworld.com)
