I am not sure I got you there.
Why is Inter-caste marriages is 'kalyug' ?
What happened to 'Ek pita ekas ke hum barak' ?
Ek pita ekas ke hum barak yes i am agree with that,
an dasam says same thing
ਜੇ ਜੇ ਸਹਿਤ ਜਾਤਨ ਸੰਦੇਹਿ ॥ ਪ੍ਰਭ ਕੋ ਸੰਗਿ ਨ ਛੋਡਤ ਨੇਹ ॥
जे जे सहित जातन संदेहि ॥ प्रभ को संगि न छोडत नेह ॥
Those who consider the castes illusory, they do not abandon the love of the Lord.
ਤੇ ਤੇ ਪਰਮ ਪੁਰੀ ਕਹ ਜਾਹੀ ॥ ਤਿਨ ਹਰਿ ਸਿਉ ਅੰਤਰੁ ਕਛੁ ਨਾਹੀਂ ॥੨੧॥
ते ते परम पुरी कह जाही ॥ तिन हरि सिउ अंतरु कछु नाहीं ॥२१॥
When they leave the world, they go to the abode of the Lord, and there is no difference between them and the Lord.21.
ਜੇ ਜੇ ਜੀਯ ਜਾਤਨ ਤੇ ਡਰੈ ॥ ਪਰਮ ਪੁਰਖ ਤਜਿ ਤਿਨ ਮਗਿ ਪਰੈ ॥
जे जे जीय जातन ते डरै ॥ परम पुरख तजि तिन मगि परै ॥
Those who fear the castes and follow their path, abandoning the Supreme Lord.
ਤੇ ਤੇ ਨਰਕ ਕੁੰਡ ਮੋ ਪਰਹੀ ॥ ਬਾਰ ਬਾਰ ਜਗ ਮੋ ਬਪੁ ਧਰਹੀ ॥੨੨॥
ते ते नरक कुंड मो परही ॥ बार बार जग मो बपु धरही ॥२२॥
They fall into hell and transmigrate again and again.22.
but there is one discipline in the world..Hindus follow their path and Sikhs follow their faith..if you are Sikh ,be a true Sikh,,if you are hindu be a hindu ...what will happen if we mix these all faiths ,,hindus will never sikh faith..and sikhs will never follow hindu faith..what will happen then????destruction , fighting ...........guru ji are not agianst inter caste marriage,guru ji says that if u gonna marry with muslim girl,,then make sure u belive in one dharma and faith,,u should join muslim religon or that girl should come in sikhism..make a decision,,don t let dharma die in your life////[my opinionss]
