When I read this lines and try to understand the meaning one thing comes to mind.
Why do people still suffer even though they recite Bani daily?
What it mean is that when I am one with TRUTH negative thoughts and vices do not touch me.
I agree with the answer above.
To answer your last part of the question.
Why do people still suffer even though they recite Bani daily?
Please note reciting does not make it, they must live the massage of the BANI.
Please refer to:
ਰਾਮ ਰਾਮ ਸਭੁ ਕੋ ਕਹੈ ਕਹਿਐ ਰਾਮੁ ਨ ਹੋਇ ॥
ਗੁਰ ਪਰਸਾਦੀ ਰਾਮੁ ਮਨਿ ਵਸੈ ਤਾ ਫਲੁ ਪਾਵੈ ਕੋਇ ॥੧॥(ਮ:੩, ਪੰ:੪੯੧)
Everyone recites RAM RAM (some name of the Creator) but saying / reciting alone has no value,
Only when RAM (Creator’s virtues) is imbibed into one’s mind (and one lives their life accordingly) only then can one enjoys the fruits.
