Whether you believe in God or not does not matter much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life.
(The real brahmin is the one who:) ... has crossed beyond duality ...knows no this shore, other shore, or both ...(is) settled in mind ... without inflowing thoughts ...is without attachment ...endures undisturbed criticism, ill-treatment and bonds, (and is) strong in patience ...(is) without anger, devout, upright, free from craving, disciplined and in his last body ...has experienced the end of his suffering here in this life, who has set down the burden, freed!
This existence of ours is as transient as autumn clouds To watch the birth and death of beings is like looking at the movements of a dance. A lifetime is like a flash of lightning in the sky, Rushing by, like a torrent down a steep mountain.
