Second Nephi 4:24

And by day have I waxed bold in mighty prayer before him; yea, my voice have I sent up on high; and angels came down and ministered unto me.

Nephi first prayed, and then angels ministered to him. What kind of a mighty prayer brings down angels? How did Nephi learn how to pray this way? He himself gives us the answer at the end of his writings. Nephi taught: "For behold, again I say unto you that if ye will enter in by the way, and receive the Holy Ghost, it will show unto you all things what ye should do" (2 Nephi 32:5).
