One earns a lot of vices by ego inflation due to caste

Guruji says 'jaat ka garb na keeje moorakh gavaara is garaab te
khatiye bahut vikara'(Take not pride in your caste o fool one earns a
lot of vices due to this pride.Many Punjabi singers placed their caste
above Sikhi.Perhaps the Jatts started it.Now others are also not
lagging behind.
