Buddha taught rebirth. He cited numerous examples in suttas of post-mortem rebirth. He showed the cause and effect relationship between beneficial and non-beneficial intentional actions and the nature of rebirth of one's rebirth in his discussion of dependent origination and its proper subset, kamma and kamma-vipakha. This teaching is consistent with his primary messages contained in The Four Noble Truths: Life is dukkha brought on as a result of our attachment and clinging to all manner of defilements: hindrances, taints, the aggregares, fetters, and fermentations. This reality of life can be changed for the better by us and only us. The agent of change is within our own personal control. He told us the exact method of change in The Noble Eight Fold Path, The Middle Way. There is no other solution, no special indulgences we can buy, no get out of jail free cards to be won; no other magical means of escape, especially not constructing and debating what and why we don't like what we read in The Pali Canon.
So...."Suck it up!" Just do it! Left foot, right foot1 The journey begins with but a single step. One step at a time. Simply begin by implementing just one beneficial thing in our lives today, which isn't in accordance with Buddhas instructions in The Noble Eight Fold Path. Don't stare up the steps. Step up the stairs. Go for it!
What Makes an Elder? :
A head of gray hairs doesn't mean one's an elder. Advanced in years, one's called an old fool.
But one in whom there is truth, restraint, rectitude, gentleness,self-control, he's called an elder, his impurities disgorged, enlightened.
-Dhammpada, 19, translated by Thanissaro Bhikkhu.
