There is no meditation without wisdom, and there is no wisdom without meditation. When a man has both meditation and wisdom, he is indeed close to nirvana.
Believe nothing just because a so-called wise person said it. Believe nothing just because a belief is generally held. Believe nothing just because it is said in ancient books. Believe nothing just because it is said to be of divine origin. Believe nothing just because someone else believes it. Believe only what you yourself test and judge to be true.
Believe nothing on the faith of traditions, even though they have been held in honor for many generations and in diverse places. Do not believe a thing because many people speak of it. Do not believe on the faith of the sages of the past. Do not believe what you yourself have imagined, persuading yourself that a God inspires you. Believe nothing on the sole authority of your masters and priests. After examination, believe what you yourself have tested and found to be reasonable, and conform your conduct thereto.
(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!
One who does not rouse themself when it is time to rise, who, though capable, is full of sloth, whose will and thought are weak, that lazy and idle person will never find their way to true knowledge.
Don't blindly believe what I say. Don't believe me because others convince you of my words. Don't believe anything you see, read, or hear from others, whether of authority, religious teachers or texts.
Through zeal, knowledge is gotten, through lack of zeal, knowledge is lost; let a man who knows this double path of gain and loss thus place himself that knowledge may grow.
