Answer

In Jain stories, the person commonly associated with turning iron into gold is Nāgārjuna.

Explanation

Nāgārjuna is remembered in Jain narrative tradition as a highly learned person connected with rasa-vidyā or alchemical knowledge. In popular Jain stories, he is described as someone who had the ability to transform base metals like iron into gold.

However, this is generally understood as part of traditional storytelling, not as a central Jain spiritual teaching.

Spiritual Understanding

Jain Dharma does not consider making gold or gaining supernatural powers as the true goal of life. Such stories often teach that:

• Worldly powers are temporary.
• Wealth cannot give liberation.
• True greatness lies in right faith, right knowledge, and right conduct.

Takeaway

The Jain story figure known for making gold from iron is Nāgārjuna, but Jain Dharma teaches that spiritual purity is far greater than material wealth.
