Everything happens with a reason and purpose, good or bad, and even those events that they call accidents.
Do you know karma???
Karma (Sanskrit: कर्म IPA: [ˈkarmə] ( listen); Pali: kamma) in Indian religions is the concept of "action" or "deed", understood as that which causes the entire cycle of cause and effect (i.e., the cycle called saṃsāra) originating in ancient India and treated in the Hindu, Jain, Buddhist, and Sikh religions.
For what I understand it means...Whatever you do to others will be done unto you...
So continue doing good things, and If you haven't,...START NOW!
