This annual retreat is ongoing training for those students who are interested in the principles and practices of sadhana.
If you are an AHS member and are considering joining this group the first step is to contact Tara ( email@example.com@arat ).
She can give you more information and arrange for you to discuss your interest with Lama Shenpen. If Lama Shenpen feels that joining the sadhana group would be a helpful next step for you then there is a process of mentored training in advance of the retreat to introduce you to the practices involved.
This year, the event is online only.
