Filled with the Spirit of the Lord

Lehi was given a vision in which the Savior and His apostles appeared to him.  The Savior gave Lehi a book. and told to read.  We don't know what was contained in this book, but we're told:

1 Nephi 1:12 And it came to pass that as he read, he was filled with the ^aSpirit of the Lord.

We may not have the same book Lehi was given, but we have the scriptures and other sacred works that we've been also commanded to read.  As we do so diligently, we will be blessed as Lehi was, and we can be "filled with the Spirit of the Lord".
