This story describe very clearly how a particular religion view the so-called Universal Truth. Most will claim that their version is the CORRECT one and would dismiss other religions.
Buddha had always been very democratic about ones' faith and not to judge others' belief. Buddha always encourage his disciples to take the good points of other religion.
The following is yet another example of what Buddha teach regarding our approach/ attitude towards other religions/ faiths.
The Kalama Sutta
The Buddha and several of his monks traveled through the Kosala country and entered a town of the Kalama people called Kesaputta. The Kamala people told the Buddha that many monks and brahmans had come to Kesaputta before him. Each of these religious men had expounded their own doctrines and reviled the doctrines of others. "Venerable sir," they asked the Buddha, "Which of these reverend monks and brahmans spoke the truth and which falsehood?"
Here the Buddha gave one of his most widely quoted teachings (Thanissaro Bhikkhu translation):
"Of course you are uncertain, Kalamas. Of course you are in doubt. When there are reasons for doubt, uncertainty is born. So in this case, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted and carried out, lead to harm & to suffering' -- then you should abandon them."
By the same token, "When you know for yourselves that, 'These qualities are skillful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted & carried out, lead to welfare and to happiness' -- then you should enter & remain in them."
By gently asking them questions, the Buddha guided the Kalamas to understand that teachings based in greed, hate and delusion are unskillful. Teachings absent of greed, hate and delusion are skillful. By applying these criteria, we can understand truth from falsehood.
