I guess you area student of ChNN. If this is indeed the case then you should have received the lung for this practice. If you are not a student of ChNN then I would recommend going to see him and asking him directly. It would be a very nice thing to do either way. Good luck with the practice and best wishes.
The Blessed One said:
"What is the All? Simply the eye & forms, ear & sounds, nose & aromas, tongue & flavors, body & tactile sensations, intellect & ideas. This, monks, is called the All. Anyone who would say, 'Repudiating this All, I will describe another,' if questioned on what exactly might be the grounds for his statement, would be unable to explain, and furthermore, would be put to grief. Why? Because it lies beyond range." Sabba Sutta.
