In Jainism, the term "Tirth" refers to a sacred place of pilgrimage associated with the lives of the Tirthankaras, or a spiritual ford that helps souls cross over the cycle of birth and death (samsara). "Svargvasi" means 'one who has gone to heaven,' and "sadhu" refers to a monk or ascetic.

The phrase "Una tirth Svargvasi sadhu" appears to refer to a Jain monk (sadhu) who was associated with the Una Tirth (a pilgrimage site at Una), and who has passed away (Svargvasi, i.e., attained heavenly abode after death). In Jain tradition, the passing of a sadhu is marked with respect, and their memory is often associated with the tirtha where they resided or served.

If you are referring to a specific sadhu from the Una Tirth who has become Svargvasi, further details could help clarify your question. In Jainism, the lives and teachings of such monks are remembered for their spiritual discipline and contribution to the community. However, ultimate liberation (moksha) is the highest goal, while going to heaven (svarga) is still within the cycle of birth and death (samsara).

If you have a more specific question about Una Tirth, sadhus, or Jain teachings about life after death, please provide more details!
