I live in a mansion.  There are so many rooms, and so many doors, that it would take more than a lifetime to explore what is in them all.  From one room, I can explore the sciences, and watch the progression of the stars and planets.  I can chart the known universe and discover things that it has taken mankind centuries to understand.
From another, I can learn the religions of the world, make connections with things divine, and come to a deeper understanding of why people are the way they are.
From another, I can become my own symphony, and follow the practices of the master composers.  I can perfect the principles they have learned and carry them on to new levels.
There is a room in my house where I can practice medicine and learn how the human body works.  In this room, I can also learn how to strengthen the powers within my own body through exercise, activity, proper nutrition and rest.
In one of the larger wings of my mansion, I can enter a fantastic world with creatures and people that most people only meet in dreams and movies.  I can converse with them, and in essence, leave the world entirely through time machines and spaceships.
I have rooms that bare the perfect resemblance of locations all around the globe.  I have been to Egypt, China, South America, and Africa without having to leave my home.
In my favorite room, I have met the Savior and His prophets.  I have come to know God, and converse with Him regularly.  I have met Adam, Enoch, Abraham, and John the Baptist.  I have met the reformers and those who took part in the great restoration of the Gospel.
I have visited many of the rooms in my mansion, and plan to visit many more.

My house is small, and my means are meager.  But in every room, there are books.
