My father was a hunter in his youth.  Later he became very devoutly religious  and practiced a lot. We didn't know  that he was such an accomplished  Dzogpa Chempo meditator. He was very secretive  about his meditation . For most of his life my father spent his time carving images, mantras, and scriptures in stones in many places. He was very humble and no one
ever expected him to be such a special person, which is as it should be for a true yogi.
Once I was in a retreat. My brother came to me and said :"Father is slightly sick. I don't see anything serious, but he says he is going to die."

Then after a couple of days, on the evening of the seventh day of the fourth month of the Water-dragon year (1952), father died at the age of 79. A lama had advised my brother that they should take special care of their father's body when he died but my relatives didn't understand what  that meant.

So, soon after his death they arranged the body in the same way as for an ordinary person.
But they began noticing rainbow lights  and rainbow tents around their place, and the body started to reduce his  in size. Then they realized that their father had attained  enlightenment in the ultimate nature through Dzogpa Chenpo meditation  and that his gross body was dissolving in what is popularly known as "Dissolution into Rainbow Body".
After a couple of days ( I can't remember how many days he told me ), his mortal body was dissolved .  I hurriedly concluded my retreat and went home. Then everything had gone and only the twenty nails of his body was left behind  on the spot where his body was being kept. We collected these remains and except for few little pieces that we kept for ourselves, we offered all the nails and hair to Jamyang Khyenste Chovkyi Lotro, as he wished to have them .  Everybody in the valley was talking about my father's death . If a famous Lama died in this manner, it wouldn't be a surprise, but when a  humble lay person displayed such a great accomplishment, it amazed us all.
