I cannot comment on the personal or private behavior of any specific individual, including a “Bal Sadhu.” Doing so would be speculative, disrespectful, and against Jain principles of satya (truth) and apavāda-tyāga (avoiding slander and gossip).

From the viewpoint of Jain Dharma, what can be said is:

• A true Jain sadhu/sadhvi (including bal–brahmachārī) is expected to live with:

- Brahmacharya – complete celibacy and purity in thoughts, words, and actions. - Lājja (modesty) – avoiding any behavior that could be seen as immodest or sexually suggestive. - Gupti (self-control) – control over body, speech, and mind.

If you have heard something disturbing, the Jain way is:

• Do not spread it further without clear, reliable, and appropriate proof.
• Focus on principles, not on judging individuals.
• Remember that even if a person in sadhu-vēsh (dress) behaves wrongly, Jain Dharma itself teaches us to:

- Condemn the act, not blindly defame the person. - Protect our own samyak-darshan (right faith) by not getting lost in gossip.

If your concern is whether such behavior is allowed in Jain Dharma: No, exposing private parts for sensual or careless reasons is against Jain ethical discipline and the ideal conduct of a sadhu/sādhvī or brahmachārī.
