None married, none contributed to the gene pool before they departed this earth - {{ sad! }}
Currently reading a book explaining Buddhism, having just read a few core ideas of Hinduism, and I'm reminded of something I learned at 17 in Religions of the World: for the most part, the message is the same. Be kind. Do good deeds. Detach from material things; even detach from all concerns of the ego; take care of your body and your peace of mind; do not fear death; etc.
The elderly, as death looms, will often start seeing people who died. It would be easy to write it off as just another delusion of dementia. But then, why don't they hallucinate their son who lives a thousand miles away? Their daughter who has been in Germany for decades, his neighbors, anyone who is still above ground and still breathing. No. They see those who've died. Along with any number of YouTube videos from people who survived the no-pulse, no brain activity (call it dead, or not) - I have hope that maybe we really DO meet again on the other side!
I cannot imagine losing four outta five brothers. God bless you!
