Following happened to me: I took randomly a book on the last Shabbat and started read. I've read there an explanation of a certain pasuk which I saw for the first time. Leaving out many details but after Shabbat I happened to listen to a shiur and the Rabbi started to speak off topic and told exact the words which I read in the book a few hours before.
Is there a mention of such a phenomenon in our sfarim? It happened already a few times to me that I learned the same thing in between a few hours from two different sources. I would like to see some sources which may explain what the exact message is, that Hashem is sending me.
