Harsimran ji,
You said that One line or the whole Shabad, Guru’s Word doesn’t change meanings Lalihayer Ji. Here are some tuks from Gurubani. If we take these literally without taking into consideration whole shabad and context, do you agree with literal meaning.
Guru Nanak Dev says on Page 153, Line 5
ਹਉ ਪਾਪੀ ਤੂੰ ਨਿਰਮਲੁ ਏਕ ॥੧॥
I am a sinner - You alone are pure. ||1||
Guru Ram Das says Page 167, Line 5
ਮੇਰੇ ਰਾਮ ਹਮ ਪਾਪੀ ਸਰਣਿ ਪਰੇ ਹਰਿ ਦੁਆਰਿ ॥
O my Lord, I am a sinner; I have come to Your Sanctuary, and fallen at Your Door, Lord.
Guru Ram Das says on Page 172, Line 11
ਹਮ ਅਪਰਾਧ ਪਾਪ ਬਹੁ ਕੀਨੇ ਕਰਿ ਦੁਸਟੀ ਚੋਰ ਚੁਰਾਇਆ ॥
I am a sinner - I have committed so many sins; I am a villainous, thieving thief.
Guru Nanak Dev says on Page 228, Line 9
ਹਮ ਪਾਪੀ ਨਿਰਗੁਣ ਕਉ ਗੁਣੁ ਕਰੀਐ ॥
I am a worthless sinner, without merit. What merit do I have?
Guru Nanak Dev says on Page 12, Line 4
ਨਾ ਹਉ ਜਤੀ ਸਤੀ ਨਹੀ ਪੜਿਆ ਮੂਰਖ ਮੁਗਧਾ ਜਨਮੁ ਭਇਆ ॥
I am not celibate, nor truthful, nor scholarly. I was born foolish and ignorant into this world.
Guru Arjan Dev says on Page 51, Line 17
ਭੂਲਹਿ ਚੂਕਹਿ ਬਾਰਿਕ ਤੂੰ ਹਰਿ ਪਿਤਾ ਮਾਇਆ ॥੧॥
Like a foolish child, I have made mistakes. O Lord, You are my Father and Mother. ||1||
Guru Ram Das says on Page 172, Line 7
ਹਮ ਅਹੰਕਾਰੀ ਅਹੰਕਾਰ ਅਗਿਆਨ ਮਤਿ ਗੁਰਿ ਮਿਲਿਐ ਆਪੁ ਗਵਾਇਆ ॥
I am egotistical and conceited, and my intellect is ignorant. Meeting the Guru, my selfishness and conceit have been abolished.
