For myself, I believe in Karma and rebirth. There is an entire thread on this, so lets not rehash it here.
So each action you make there is an outcome for it and if you do not experience that outcome in this life you will in future rebirths. So, HH Dali Lama has created much merit in previous lives, and as a Bodhisattva, he continually creates more merit
to benefit all universal living beings.
