The ultimate answers are only what Kelsang Gyatso says they are. Of couse, they are not.
While Kelsang Gyatso's books are generally worthy introductions to Buddhism and possible gateways to deeper effort through teachings beyond NKT, NKT leadership has severely tarnished any chance for a positive legacy for Kelsang Gyatso.
Kelsang Gyatso's political sectarianism, NKT's caustic public relations assault and their banning of teachings beyond NKT undermined their potential contributions.
What a waste.
Worse, they have stunted or derailed thousands interested in exploring Buddhism. They have abused hopes, good will and financial contributions for little more than real estate development and self gratification.
While Kelsang Gyatso and NKT leadership thrilled their egos, their net contribution has been negative.
They have stained the gifts of Shakyamuni (founder of Buddhism 2,500 years ago) and Tsongkhapa (founder of New Kadampa Buddhism 500 years ago).
