Losing a parent makes you really look at shyt different. When I lost mine I did

The gospel. Nas hit it on the head when he said:
Your mother's the closest thing to
God that you ever have kid
When my mother passed, the world became different and my vision on life got clearer with time. You start to see those people that you called "friends" are just mere objects within the matrix because they don't know your pain like YOU do. All the material in the world doesn't matter compare to a moment with your own mother or even father. Spiritually I killed my past so I can somehow maintain focus for the future after years of mourning. Some people's spirits die with their love ones while some become born again.
In the Rock's case, dude probably seen what real because judging by his actions lately, he found independence from those that kept treating him like a puppet on strings.
