“Ask and it will be given to you;
seek and you will find;
knock and the door will be opened to you.
For everyone who asks receives;
the one who seeks finds;
and to the one who knocks, the door will be opened."
- Matthew 7:7-8

I propose some doors to open my little world: Science, Literature, Anthropology, Occult, Mineralogy, Law, Painting and Voyage.
One is not enough, but All is too much.
