I have lived as a hermit in different situations: one was in a laura (a loose collective of other hermits who share certain things like daily Mass, Saturday Vespers, one shared meal per week, followed by a recreation together on Sunday. The other was alone in the bush using rain water, wood stove for heating the room and water, and a small generator for lights at night (when I could afford the petrol). There was no fridge, no small or large appliances and no toilet (I would use a bucket at night and then bury the results the next day). During the day I would dig a hole and then cover it. The grass grew very well over these spots! LOL
I learned a lot about self-reliance, but also about physical hardships. The main hardship for me was dealing with spiders and snakes and insects. The advantages were the beauty of the bush, especially the wildlife, and the quiet time to spend with God. The closest town had Mass three Sundays a month and a communion service on the fourth.
I think living the hermit life is a good thing for anyone to try for awhile - just to learn how to live without the so-called necessities of life and to focus on living closer to nature. It is also a good opportunity to grow spiritually. I am glad I tried it, especially in different ways and I think it has influenced the way I live my life now, even though I now live in relative comfort in a small country town.
