Re: Buddhist Technological Shabbat
Hola ShanJieshi! En primer lugar, me alegra ver a otro hispano-hablante por el foro 
Regarding your post, my current teacher -Ajahn Sona- (in the line of what Bunks has already shared), recommends us to have a day of observance per week. He calls it a day dedicated to the dhamma. I think "internet fasting" and being present without any screens is a great way to practise as well, definitively complementary!

War
Once again a war on the screens... Buddhist kiosks take to the streets to offer their colourful crutches for the mind that yearns for the ease of comfort. Instant Sadhanas and thousands of posters to paste on social media.
They forget that it is this suffering-filled peace that makes it possible for war to thrive.
Re: My library
@Jeroen One of the big problems for students is reading spiritual books without
help, because words really don’t touch the truth; you have to look beyond
them.
My Master says :"When I taught the Dharma in Thailand, India, and China, I met
people in monasteries who, as monks, studied the Sutras (which are better
than most books) on a daily basis but hadn’t grasped the essence and
therefore hadn’t liberated themselves at all from the mind in preparation to
advance on the path. People go to temples, do initiations, and follow practices
for years without having the slightest idea of what they’re really doing."
Re: My library
My buddhist library is modest. I have maybe 10 books and about 40 pdfs. Some of them have been key in my understanding of buddhism.
But I do find it interesting that @ShanJieshi2’s buddhist welcome letter says to only read those materials that the your teacher has approved. When I was studying with the Tibetan Buddhist Gelugpa temple, they had a similar policy. There was a cabinet with many slender, similar-looking volumes which had been written by the Rinpoche, which you could borrow.
Personally it was one of the reasons for me not to continue with that temple. Being free in searching for books and writings is a privilege, hard-won in some places in the past, and not something I am keen to let go of. Similarly it is a reason for me to not pursue becoming a monk.
