For the first time, there will be a Guhyasamaja Retreat at the FPMT Land of Joy Retreat Centre at Greenhaugh, Northumberland, in the north of the UK.
It will run from Saturday 14th to Friday 20th November, 2015, ending with a Guhyasamaja Tsok puja on the last evening. The purpose of the retreat is to deepen our understanding of the practice.
Booking details are available by email from email@example.com. Students must commit to attend for entire days at a time. It is not required that you attend for the whole week, but that would be preferred, of course.
