One day Malunkyaputta got up from his afternoon meditation, went to the Buddha, saluted him, sat on one side and said:
'Sir when I was all alone meditating, this thought occurred to me: There are these problems unexplained, put aside and rejected by the Blessed One. Namely, (1) is the universe eternal or (2) is it not eternal, (3) is the universe finite or (4) is it infinite, (5) is soul the same as body or (6) is soul one thing and body another thing, (7) does the Tathagata exist after death, or (8) does he not exist after death, or (9) does he both (at the same time) exist and not exist after death, or (10) does he both (at the same time) not exist and not not-exist. These problems the Blessed One does not explain to me. This (attitude) does not please me, I do not appreciate it. I will go to the Blessed One and ask him about this matter. If the Blessed One explains them to me, then I will continue to follow the holy life under him. If he does not explain them, I will leave the Order and go away. If the Blessed One knows that the universal is eternal, let him explain it to me so. If the Blessed One does not know whether the universal is eternal or not, etc., then for a person who does not know, it is straightforward to say “I do not know, I do not see.”’
The Buddha’s reply to Malunkyaputta should do good to many millions in the world today who are wasting valuable time on such metaphysical questions and unnecessarily disturbing their peace of mind:
'Did I ever tell you, Malunkyaputta, “Come, Malunkyaputta, lead the holy life under me, I will explain these questions to you?”’
'No, Sir.’
'Then, Malunkyaputta, even you, did you tell me: “Sir, I will lead the holy life under the Blessed One, and the Blessed One will explain these questions to me”?’
'No, Sir.’
'Even now, Malunkyaputta, I do not tell you; “Come and lead the holy life under me, I will explain these questions to you”. And you do not tell me either; “Sir, I will lead the holy life under the Blessed One, and he will explain these questions to me”. Under these circumstances, you foolish one, who refuses whom?’
'Malunkyaputta, if anyone says: “I will not lead the holy life under the Blessed One until he explains these questions,” he may die with these questions unanswered by the Tathagata. Suppose Malunkyaputta, a man is wounded by a poisoned arrow, and his friends and relatives bring him to a surgeon. Suppose the man should then say; “I will not let this arrow be taken out until I know who shot me; whether he is a Ksatriya (of the warrior caste) or a Brahmana (of the priestly caste) or a Vaisya (of the trading and agricultural caste) or a Sudra (of the low caste); what his name and family may be; whether he is tall, short, or of medium stature; whether his complexion is black, brown, or golden; from which village, town or city he comes. I will not let his arrow be taken out until I know the kind of bow with which I was shot; the kind of bowstring used; the type of arrow; what sort of feather was used on the arrow and with what kind of material the point of the arrow was made.” Malunkyaputta, that man would die without knowing any of these things. Even so, Malunkyaputta, if anyone says :”I will not follow the holy life under the Blessed One until he answers these questions such as whether the universe is eternal or not, etc.,” he would die with these questions unanswered by the Tathagata.’
Then the Buddha explained to Malunkyaputta that the holy life does not depend on these views. Whatever opinion one may have about these problems, there is birth, old age, decay, death, sorrow, lamentation, pain, grief, distress, “the Cessation of which (i.e. Nirvana) I declare in this very life.”
