Answer

In Jain tradition, it is commonly understood as Dhanya Teras, not merely Dhanteras.

Explanation

In general Indian usage, the day is often called Dhanteras, where “dhan” is commonly associated with wealth.

But in Jain understanding, the day is remembered as Dhanya Teras:

• Dhanya means blessed, worthy, or spiritually fortunate.
• Teras means the thirteenth day of the lunar fortnight.

For Jains, this day is especially connected with Bhagwan Mahavir Swami. It is traditionally associated with the period near his final liberation, and the focus is not on material wealth but on spiritual wealth such as right faith, right knowledge, right conduct, restraint, and detachment.

Spiritual Understanding

So the Jain emphasis is:

• not on increasing outer wealth,
• but on becoming dhanya through inner purity,
• remembering Bhagwan Mahavir’s teachings,
• and moving toward liberation through self-discipline and non-attachment.

Takeaway

For Jains, the more spiritually meaningful expression is Dhanya Teras — the blessed thirteenth day — rather than simply Dhanteras as a festival of material wealth.
