how bad is an ungrateful person? read below bhai gurdas' bani:
ਮਦ ਵਿਚਿ ਰਿਧਾ ਪਾਇ ਕੈ ਕੁਤੇ ਦਾ ਮਾਸੁ॥
ਧਰਿਆ ਮਾਣਸ ਖੋਪਰੀ ਤਿਸੁ ਮੰਦੀ ਵਾਸੁ॥
ਰਤੂ ਭਰਿਆ ਕਪੜਾ ਕਰਿ ਕਜਣੁ ਤਾਸੁ॥
ਢਕਿ ਲੈ ਚਲੀ ਚੂਹੜੀ ਕਰਿ ਭੋਗ ਬਿਲਾਸੁ॥
ਆਖਿ ਸੁਣਾਏ ਪੁਛਿਆ ਲਾਹੇ ਵਿਸਵਾਸੁ॥
ਨਦਰੀ ਪਵੈ ਅਕਿਰਤਘਣੁ ਮਤੁ ਹੋਇ ਵਿਣਾਸੁ ॥9॥
The meat of dog cooked in the wine was,
Along with its foul smell, kept in the human skull.
It was covered with blood stained cloth.
Covering thus, the scavenger woman (ਚੂਹੜੀ) after appeasing her lust (still polluted after the act) was carrying that
bowl.
On being asked about (the abominable covered material) she cleared the doubt,
By saying that she had covered the meat to hide it from the sight of an ungrateful person
to avoid pollution caused by his look.(9)
