The description on that page is quite succinct:
This is something I would be very interested in pursuing – a way of doing the practices of the traditional three year retreat, but alongside being a lay person living an ordinary life. Unfortunately, this program has already started, so I'm wondering if anyone knows of any other centers/teachers who offer something similar?This seven-year program is for dedicated practitioners who cannot do long-term retreat, but wish to live a life imbued with intense practice. The curriculum consists of practices done in the traditional Vajrayana three-year solitary retreat adapted for the modern practitioner living in the “world.”
I'm sure there is much lively discussion/debate to be had around the advantages of doing the 3 year retreat in the traditional way it was conceived, and I am certainly open to starting and engaging that discussion, but I am primarily interested to find out if anyone knows other places doing similar things.
