Answer

In Jain Dharma, Lord Vardhman Mahavira and Shivshankar are not described as family, and Jain texts do not present them as “god-to-god acquaintances” in the way you are asking.

Explanation

• Lord Mahavira is the 24th Tirthankara of Jainism.
• Tirthankaras are not creator gods; they are fully enlightened beings who show the path to liberation.
• Shivshankar is a revered deity in Hindu tradition.
• Jainism does not teach that Mahavira and Shivshankar are the same, or that they share a divine relationship like family.

So, from the Jain point of view:

• Mahavira is a spiritual master and liberated soul in the making of liberation.
• Shiva is not part of the Jain line of Tirthankaras.
• There is no Jain doctrine that says they “know each other as gods.”

Spiritual Understanding

Jain Dharma focuses on self-purification, right faith, right knowledge, and right conduct. It does not center on worship of a creator god.

So the important point is:

• Mahavira shows the Jain path to liberation.
• Other deities may be respected in a cultural or devotional sense, but Jainism does not place them in the same spiritual category as a Tirthankara.

Takeaway

In Jainism, Lord Mahavira and Shivshankar are not considered family, and Jain teaching does not describe them as knowing each other as gods. Mahavira is honored as a Tirthankara and spiritual guide.
