On November 22, we received a reply from Ato Rinpoche. It was short and to the point, clearly responding to our request. Here is the response:
Greetings to the signatories of the letter below!
I am reticent by nature and by training reluctant to criticise the behaviour of others. In the present circumstances, however, I do now plainly state that the abusive behaviour outlined in the letter by eight Rigpa students last year – if it is true, and I have no reason to doubt it – is not acceptable to me.
For sound advice on the Teacher/Pupil relationship I would recommend reading Patrul Rinpoche and heeding the advice repeatedly given by the Dalai Lama.
