My suggestion would be to begin with The Four Noble Truths, which include the Noble Eight Fold Path. This is Buddha's central message to all beings and forms the foundation for his justification for being of assistance to all beings within the samsaric realms. You can research this through the writings of Bhikkhu Bodhi, or you may begin here:http://www.accesstoinsight.org/lib/study/truths.html

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.
