In relation to the first shabad posted my reasoning: - Guru ji' Gate is Guru's Bachan (Gurbani - Sri
Guru Granth Sahib ji). Our "mind" needs to be washed to realise God in us and around us.
ਭਨਤਿ ਨਾਨਕੁ ਕਰੇ ਵੀਚਾਰੁ ॥
bhanath naanak karae veechaar ||
Prays Nanak, practice contemplation,
ਸਾਚੀ ਬਾਣੀ ਸਿਉ ਧਰੇ ਪਿਆਰੁ ॥
saachee baanee sio dhharae piaar ||
and enshrine love for the True Word of His Bani.
ਤਾ ਕੋ ਪਾਵੈ ਮੋਖ ਦੁਆਰੁ ॥
thaa ko paavai mokh dhuaar ||
Then, you shall find the Gate of Salvation.
( Ang 661)
ਬਾਣੀ ਰੋਕਿਆ ਰਹੈ ਦੁਆਰ ॥
baanee rokiaa rehai dhuaar ||
Restrained by Gurbani, the mind remains indoors;
ਤਉ ਮਨੁ ਮਤਵਾਰੋ ਪੀਵਨਹਾਰ ॥੨॥
tho man mathavaaro peevanehaar ||2||
drinking in this Nectar, it is intoxicated. ||2||
(Ang 344)
ਪ੍ਰਭ ਕਹਨ ਮਲਨ ਦਹਨ ਲਹਨ ਗੁਰ ਮਿਲੇ ਆਨ ਨਹੀ ਉਪਾਉ ॥੧॥ ਰਹਾਉ ॥
prabh kehan malan dhehan lehan gur milae aan nehee oupaao ||1|| rehaao ||
Speaking of God, filth and pollution are burnt away; This comes by meeting with the Guru, and not by any other efforts. ||1||Pause||
(ang 1305)
