9. The Forest Suttas
Ayoniso (or Vitakkita) Suttaṃ
Want of Method (or Fancies)
A certain brother was once staying among the Kosalese in a certain forest-tract.
And at that time that brother was occupied during his siesta with evil and wrongful thoughts, to wit, with sensual, malevolent, and cruel thoughts.
Then the deva who haunted that forest-tract,
moved with compassion for that brother,
desiring his welfare,
and wishing to agitate him,
drew near and addressed him in the verse:
Thou hast no thorough method in thy thought, Good sir, and hence art thou inebriate With thine ideas. Renounce these muddled ways. Marshall thy thoughts in ordered governance Anent the Master, Norm, and Brotherhood; From virtue's code let there be no recoil. So shalt thou reach [the goal of] joy, of zest And bliss and full assurance. Thence in joy Abounding thou shalt make an end of i11.
Then that brother, agitated by the deva, was greatly moved.
 It is never easy to find fit rendering for the important idiom [a]yoniso manasikāra. See p. 131, and cf. my Buddhist Psychology (1914), 123,160, and cf. the attempt in Pss. of the Brethren, ver. 269, etc.
Thereat arose in me the deeper thought:
Attention to the fact and to the cause.
Yoni is matrix, source; yoniso is 'from' or 'qua' yoni (the ablative). The other word (in the Suttas) is just 'work of mind.' B. often paraphrases *ayoniso by an-upāya, with [out] method, plan, system. 'Muddled ways' = a-yoniṃ.
 Majjasi. The indicative, as here, very rarely occurs.
 Lit. the negative form: 'rid of doubt' (a-saŋsayo).
