"Kadva tumbada no aahar kaya muni bhagwant hata" is a question about which Jain monk (Muni Bhagwant) accepted food (aahar) made from "kadva tumbada" (bitter gourd or a specific bitter vegetable).

In Jainism, the aahar (food) taken by Muni Bhagwants (saints) is highly regulated and symbolic. There are many stories in Jain literature where Jain monks have accepted even very bitter or tasteless food offered with devotion, to show their detachment and acceptance of whatever is offered without preference.

One famous story relates to Acharya Kundkund (or sometimes other revered monks), who accepted extremely bitter food ("kadva tumbada") offered with great devotion, without showing any aversion or preference. This incident is often cited to exemplify the virtue of vairagya (detachment) and samata (equanimity), key principles in Jain ascetic life.

However, the specific details of which Muni Bhagwant exactly took "kadva tumbada" may vary by regional oral traditions and texts. The main message is the monk's practice of accepting whatever alms are offered, without desire or aversion, reflecting Jain ideals.

If you are referring to a specific Jain text or story, please provide more details, and I can try to elaborate further within the Jain tradition.
