This is a pretty common practice with Tibetan Buddhists. There’s a traditional 3 year retreat that, depending on the practitioner, involves varying levels of contact with other humans. Often times it’s no contact, with an attendant dropping off supplies outside the cave every so often. Tenzin Palmo spent 3 years in full retreat in her cave [1], for instance, out of a total of 12 years in it.
