He then begins toobserve each of the different functional consciousnesses in the firstjhŒna mind door process and discern all the types of mentality thatoccur in each functional consciousness whether it be 12 or 34.After the meditator can discern all the types of mentality that arisein each consciousness of a first jhŒna mind door process he thendiscerns the common characteristic of all mentality which is theircharacteristic of bending towards and sticking to an object. Then hesimply discerns all the 34 types of mentality present in the first jhŒnaas mentality (nŒma).After that the meditator performs the same type of discernmentand analysis of mentality of the second, third, and fourth jhŒna ofmindfulness of breathing and also of any other jhŒnas that he isable to attain using other meditation subjects.
