The next line?
Yaha shruti ved kehta, Guru bina gyaan kaisa?
Meaning: our scriptures ask how we can get True Knowledge if there is no Guru
Gyaan bina mukti kaise, aave teri dhyaan mein
Meaning: without That Knowledge, how will you even begin to comprehend liberation?
Krodh kapat tyaag kijiye, sadguru ki seva kijiye
Meaning: give up anger and deceit and focus on serving the Guru
Sadguru ki sharan lijiye, khel yeh maidan mein
Meaning: surrender to your Guru, and continue playing in this game called life.
To me, this bhajan, reflecting the beautiful Guru-shishya relationship is what is true Grace. Are we worthy of it?
