I am so sorry about your loss. I am not a Sikh Youth, I am actually an old man, almost 54 yrs old. I have lost many close to me, including both of my parents. My brothers wife died of cancer 6 yrs ago. It is still very hard for me to lose anyone close to me. I cry at the loss of people I don't even know! I am now studying to become a Sikh, so I am not very knowledgeable in this area. But, I just tell myself that perhaps this was their last incarnation. Your brother sounded like a great person but perhaps this was his time to merge with Waheguru. We can never understand death. But we must look at it as a beginning, not an end. You will see your brother again someday. In the meantime, we will keep you and your family in our thoughts and prayers. Your loss is our loss. God bless you and give you peace.
Waheguru Ji Ka Khalsa, Waheguru Ji Ki Fateh.
