Mbh 3.31.1b

It is by virtue alone that he hath acquired immortality in the flesh. Vyasa, and Vasistha and Maitreya, and Narada and Lomasa, and Suka, and other Rishis have all, by virtue alone, become of pure soul! Thou beholdest them with thy own eyes as furnished with prowess of celestial asceticism, competent to curse or bless (with effect), and superior to the very gods! O sinless one, these all, equal to the celestials themselves, behold with their eyes what Is written in the Vedas, and describe virtue as the foremost duty! It behoveth thee not, therefore, O amiable Queen, to either doubt or censure God or act, with a foolish heart. The fool that doubteth religion and disregardeth virtue, proud of the proof derived from his own reasoning, regardeth not other proofs and holdeth the Rishis, who are capable of knowing the future as present as mad men. The fool regardeth only the external world capable of gratifying his senses, and is blind to everything else. He that doubteth religion hath no expiation for his offence. That miserable wretch is full of anxiety and acquireth not regions of bliss hereafter. A rejector of proofs, a slanderer of the interpretation of the Vedic scriptures, a transgressor urged by lust and covetousness, that fool goeth to hell. O amiable one, he on the other hand, who ever cherisheth religion with faith, obtaineth eternal bliss in the other world. The fool who cherisheth not religion, transgressing the proofs offered by the Rishis, never obtaineth prosperity in any life, for such transgression of the scriptures. It is certain, O handsome one, that with respect to him who regardeth not the words of the Rishis or the conduct of the virtuous as proof, neither this nor the other world existeth. Doubt not, O Krishna, the ancient religion that is practised by the good and framed by Rishis of universal knowledge and capable of seeing all things!
