In Jain tradition, maryādā means proper conduct, dignity, restraint, and protection of ahiṃsā, brahmacarya, and aparigraha.

So the question is not simply “female singer or dancer = wrong.” The real Jain view is based on:

• intent
• modesty and conduct
• whether it increases passions
• whether it violates restraint
• whether it harms one’s vows or purity

In Jain ethics

Public singing or dancing is not automatically prohibited for every woman in every situation. But Jain tradition generally gives greater emphasis on restraint, especially avoiding:

• sensual display
• provoking attachment or desire
• loss of modesty
• entertainment that distracts from dharma

Why it may be seen as improper

If a performance is done with:

• immodesty,
• glamour meant to arouse attachment,
• pride,
• greed,
• or entertainment that weakens spiritual discipline,

then it can be considered against maryādā from a Jain ethical standpoint.

Why it may still happen

In worldly life, many people do not follow strict Jain vows. So such activities may occur socially or professionally, but that does not mean they are ideal according to Jain discipline.

Jain standard

A Jain aspirant should ask:

• Does this support restraint?
• Does this increase passions?
• Is it within modest conduct?
• Is it compatible with my vows and spiritual aim?

Conclusion

So yes, from a strict Jain perspective, public dancing or singing done in a way that breaks modesty or increases attachment would generally not be encouraged. But Jainism does not make a blanket condemnation of all singing or dance; it judges by maryādā, purpose, and inner discipline.

If you want, I can also explain this according to Shravak dharma and sanyam in simple Jain terms.
