I like the shelves with my favorite books, but not having them within reach, I love my virtual library in ebooks where I have what I like to read and meditate, I have not visited a library for a long time, the last time I went to the sound library section where there were countless books, writers and contemporary musicians, the digital is effective but do not let it absorb us, a printed book is a good treasure, and sometimes rest the view of the blue light is necessary.
