如是我闻：一时佛在骄萨罗国，羁舍子村落，其族人是迦摩罗族姓的后代。
I heard thus. Once the Blessed One, while wandering in the Kosala country with a
large community of bhikkhus, entered a town of the Kalama people called
Kesaputta.
……他们听闻佛来了，就来拜见他……向他说：「世尊，有些梵志和出家人来到羁舍子，他们只解说弘扬他们自己的教义，而蔑视、非难、排斥其他教义。然后又来了其他的梵志出家人，他们也同样的只解说弘扬他们的教义，而蔑视、非难、排斥其他的教义。但是对我们来说，我们一直都怀疑而感到迷惘，不知道在那些可敬的梵志方外人当中，到底谁说的是真实话？谁说的是妄语？」
... They went to see the Blessed One ... said to him: "There are some monks and
Brahmans, venerable sir, who visited Kesaputta. They expound and explain only
their own doctrines; the doctrines or others they despise, revile, and pull to
pieces. Some of other monks and Brahmans too, venerable sir, come to Kesaputta.
They also expound and explain only their own doctrines; the doctrines of others
they despise, revile, and pull to pieces. Venerable Sir, there is doubt, there
is uncertainly in us concerning them. Which of these reverend monks and Brahmans
spoke the truth and which falsehood?"
佛说：「是的，迦摩罗人啊！你们的怀疑，你们的迷惘是正当的，因为对於一件可疑的事，是应当生起怀疑的，迦摩罗人啊！你们要注意：
"It is proper for you, Kalamas, to doubt, to be uncertain; uncertainty has
arisen in you about what is doubtful. Come, Kalamas.
不可听信因为你曾听过很长的一段时间；
Do not go upon what has been acquired by repeated hearing;
不要盲从传统仅因为它很多代以来人们这么做；
nor upon tradition;
不要妄听谣言；
nor upon rumor;
不要肯定它因为它符合你的教义；
nor upon what is in a scripture;
不可单靠论理或推测；
nor upon surmise;
不要妄下定论，依赖着你所看所听；
nor upon an axiom;
不可单看事物的外相；
nor upon specious reasoning;
不可执持你喜爱的任何见解和意见；
nor upon a bias toward a notion that has been pondered over;
不可因某事物似有可能而信以为真；
nor upon another's seeming ability;
不可因为你出於你对你导师的崇敬和推荐而接受任何想法；
nor upon the consideration, 'The monk is our teacher.'
迦摩罗人啊！你应超越意见和信念，只有在你确知某事是不善，当接受，修持和圆满修习后导致更多嗔恚，更多贪欲，和更多愚昧，因为你知道当你嗔恨、贪欲和愚昧时，这并不符合你信仰或意见，要知道，嗔、贪、痴是普遍被人诃责的，他们是无益的，并且应该避开。……反之，当你确知某事是善，当你信受奉行时会导致慈悲心，离欲和智慧，这些美德充份的允许你训练安宁的心，智者称赞慈悲的心，离欲和智慧，这就可以接受。这应是你审察真理的真伪，以及决定那一种才是正确的修行。」
Kalamas, when you yourselves know: 'These thing are bad; these things are
blamable; these things are censured by the wise; undertaken and observed, these
things lead to harm and ill,' abandon them. ... Kalamas, when you yourselves
konw: 'These things are good; these things are not blamable; these things are
praised by the wise; undertaken and observed, these things lead to benefit and
happiness,' enter on and abide in them."
……迦摩罗族姓子听闻了佛所说的，欢喜奉行。
... "Venerable sir, may the Blessed One regard us as lay followers who have gone
for refuge for life, from doday."

Anguttara Niikaya
以上佛言摘自《索达吉堪布回济群法师有关藏传佛教19问》，是索达吉堪布在解释密宗的双身修法时引用的。堪布认为，判定破戒与否有两个标准：一个是有无离贪 之心与方便善巧，若未被贪心所摄，则可对所谓破戒之淫行作相应开许；另一个是是否远离了执著，若守持戒律却脱离不了执著，则其戒行究竟是不得清净。引用的 佛言是为了阐明第二个标准。
