Commentary to Samaadhisutta, K S IV, 80.

Venerable Yuttadhammo,
  here is the sentence; <samaadhin ti, citt'ekaggata.m: ida.m sutta.m citt' egaggataaya parihaayamaane disvaa, 'imesa.m citt' ekaggata.m labhantaana.m kamma.t.thaana.m phaati.m gamissattii' ti natvaa, kathita.m>
  My question: phaati.m. The Thai translation uses the term wetnurse. Thus, samaadhi is like a wetnurse so that citta knows only one object. The dict. says: increase, not wetnurse.
What is your opinion,, thank you.
respectfully,
Nina.
