Of course prayer works, and ironically, science proves the relationship between mind and how it effects phenomena.
The purpose of my post is to point out that this person that many see as a Buddhist Master is saying that prayer doesn't work, and claims such as this are amongst the many things that disqualify him as a valid reliable Teacher.
He is teaching that religion is inadequate, that prayer doesn't work, that his lineage Gurus and tradition are invalid, that Buddha is wrong, that violent weapons and shooting living beings are wonderful, that ethnic cleansing of his own people through a cultural revolution is good and something to laugh about, that destroying the Three Jewels for political and financial gain is valid, that making people homeless and unable to find jobs and schooling and medical care is part of the Buddhist Way of Life.
Nowhere in the Lamrim or Vajrayana does it give a list of actions such as these as being the qualities of a valid Buddhist Teacher. And yet, people are adamant about seeing this person as a respectable teacher. That shows a lack of wisdom and common sense. We will never achieve realizations through following invalid Teachers, especially criminals trying to destroy the lineage you're trying to follow!
