It is true that people get prosperous, fame, power and growth when they take pictures with the Dalai Lama and donate to the CTA in the last 59 years or so. However, this has proven to be wrong with many corruptions and sex scandals to be exposed in recent years. People are starting to see how ineffective the CTA is and how good they are in selling the Dalai Lama's fame for selfish gain.
It is very clear to many that the CTA has not done what they are supposed to and they have not achieved anything for the Tibetan cause which is now inexistent. No one remembers why some of the Tibetans are living in exile. No one remembers what the Dalai Lama's function is. All they remember is the Dalai Lama got really famous around the world but the Tibetans in exile, especially in India, after 60 years are still sweater seller in the winter.
Anyone smart would really not want to have any associations with them. So it is definitely a right move for the Karmapa Thaye Dorje to ignore the Dalai Lama with his son, Sharmapa Rinpoche. This is the only way to grow and not be dragged down to uneding political games and problems.
