Sacca is a Pali word. It is translated as Thitsar.
There are two kinds.
In the Loki (Mundane) context, there is Samuti Sacca (Concept). It is loosely rendered as “Relative Truth”.
In the Lokotra (Supra-mundane), there is Paramattha Sacca. It is loosely rendered as “Absolute Truth”.
It is important not to mix the two and get confused.
In the lay world, “Thitsar” is taken to be “something true (but not necessarily good).
In an anecdote, a boy was struck by a poisonous snake (or similar). There was no doctor (or medicine man) nearby. So, the three : father, mother and hermit decided to rely on Thitsar.
The mother said, “I married the man even though I did not love her. May my son be cured”.
The father said, “I gave alms to the hermit, even though I do not respect him. May my son be cured”.
The hermit said, “I do not enjoy an instant being a hermit. May the boy be cured”.
The boy seemed better with each utterance of Thitsar, and was cured.
There are several Suttas which describe the “Asserveration of Truth”.
- Ratana Sutta
- Vutta Sutta
- Angulimala Sutta
