Gianiji
Waheguru ji ka khalsa,
Waheguru ji ki fateh
You have said right but presented in mannner which only confuses learner.
Gurbani tells us, Gurmukh japiye laie dhayan. It means that gurmukh while living by the principles and teachings of the Gurus when chants His glorious virtues or does keertan single minded, it is meditation. Gurbani further tells us, " Sabbh tai uttam har ki katha -Naam sunat dhard dukh latha - God speach is the highest And hearing the Naam, pain and sorrows are removed, then mind by itself is fresh and from worries" I hope it clears the contradiction. Since Gurbani tells us, "kalyug mai keertan pardhana. Therefore through the keertan possiblities of merging with God is speedy. If this keertan is not profession but devotion and this devotion turns to dhayana. And this dhayana becomes the cause of union.
