I can only talk about Buddhist monkhood. I consider myself kind of a former Buddhist (Guelukpa) and for some time I was so sure I was going to become a monk that I went to Osel Ling (Buddhist "monastery" in Spain) to live as a isolated monk for some time. To taste that kind of life. Talking to anybody (not very usual tho), long, elaborated meditations for hours 4 times a day, praying, chanting mantras, prostrations... Vegan meals...
If I wanted, I could have become a monk, but after that experience, I actually quit the sect I was following. Living as a monk is
1. Extremely boring compared to probably any other way of life
2. Busy, you have no time for anything anymore.
3. Non-sensical (unless you really believe in some ancient mithology)
Also, I think I'm high T because I just can't stop fapping at all, it's impossible for me lol
But it had some advantages: an isolated life. A lot of order. Plenty of time to develope any spiritual or philosophical opinion, insight, theory, etc... Less sexual desire (a monks life is designed for him to never get horny lol). Silence. Calm. Idk.
If you are really interested, there's a Buddhist monastery that accepts everyone (literally) as long as the person is a heavy drug addict or (if I remember it correctly) suicidal. I can search for the name. It was in an Asian country.
