I think BJR pretty much has his/her answer by now...
NKT has nothing to do with Theravada, and neither Theravadins, nor any non-NKT Buddhists are likely to recommend it.
Since this topic isn't particularly conducive to dispassion and calming the senses
I think it's best finished here.
For the record, discussion on NKT is not prohibited here at Dhamma Wheel, but it's not of relevance in the Discovering Theravada sub-forum, other than to say it's got nothing to do with Theravada.
Through corruption of the Dhamma comes corruption of the discipline, and from corruption of the discipline comes corruption of the Dhamma. This is the first future danger as yet unarisen that will arise in the future. You should recognize it and make an effort to prevent it. (AN 5.79)
Neither traceable in the Discourses nor verifiable by the Discipline, one must conclude thus: 'Certainly, this is not the Blessed One's utterance; this has been misunderstood by that bhikkhu — or by that community, or by those elders, or by that elder.' In that way, bhikkhus, you should reject it. (DN 16)
