Idhekacco puggalo lābhī hoti rūpasahagatānaṃ vā arūpasahagatānaṃ vā samāpattīnaṃ.

Here a person obtains the attainments whether accompanied by an idea of form or by an idea of formlessness, and he does not surely obtain them as he desires, nor without difficulty, nor without toil, neither does he get into nor get up from them where he desires, when he desires, and as long as he desires; if he follows this up by willing (not to fall away), he does not fall away from those attainments, if he does not so will, he does fall away from them. Such a person is said to be a person who is competent in will.
