Answer

In Jain tradition, there is no single commonly accepted historical record that identifies the first person to do maskhaman (māsakṣamaṇa).

Explanation

Maskhaman is a highly respected form of tapas, but Jain tradition does not generally preserve it as something that began with one clearly named “first” person. It is understood as part of the ancient Jain path of austerity and self-purification.

Spiritual Understanding

The importance of maskhaman is not in who did it first, but in its purpose:

• to reduce attachment to the body
• to purify the soul
• to develop patience, equanimity, and spiritual discipline

Takeaway

So, the honest Jain answer is: we do not have one definite first person known for maskhaman. It is an ancient and revered practice within Jain Dharma.
