Answer

In Jain Dharma, the brother of a Yaksha is not a single fixed concept.

A Yaksha is generally understood as a celestial or guardian deity connected with Jain tradition, especially as a Shasan Dev associated with a Tirthankar.

Explanation

If you are asking about a specific Yaksha, then the answer depends on which Yaksha you mean.

For example, Jain tradition mentions many Yakshas, such as:

• Gomukha Yaksha
• Mahāyaksha
• Trimukha Yaksha
• Yaksheshvara
• Brahma Yaksha
• Matanga Yaksha
• Dharanendra Yaksha

Their family relationships are not always described in commonly accepted Jain tradition. Jain texts mainly focus on their role as attendant deities, not on worldly family relations like “brother.”

Takeaway

Please tell me which Yaksha you are referring to, and I can answer more clearly if that information is established within Jain tradition.
