jo aaeiaa so chalasee amar s gur karathaar ||Whoever comes also goes, but permanent is the Guru, the Creator.
Whatever happens happens in hukam and it is part of the cycle of the universe.. coming and going. No one is a bad person, we're all just puppets my friend.
kar kirapaa prabh bhaettiaa maran n aavan jaao ||1||When God does kirpa, He Himself meets us, and we no longer die and come again.
It's all His sweet game - He chooses when we come out of this cycle. Don't dwell too much on these things, instead learn to accept that it does happen.
Guru Sahib kirpa karan.
