Preparing to Enter the Holy Temple
The Church provides a booklet called "Preparing to Enter the Holy Temple" to assist with temple prep. It is available on the Gospel Library app. The first time I read it was 7 months before my baptism. I re-read it today and am laughing my fool head off at my past self. Why did I need to read this so early? I had so little context in which to put the information.
However, having said that, the booklet itself is helpful for a high-level overview. But it leaves me with more questions than answers.
