What does "it " refer to in this sentence? ...gain it, does it mean to gain faith? or refer to "accustom yourself to the new conditions."?

Those of you who had faith in life after death will find it much easier to accustom yourself to the new conditions. Those of you who do not have such faith may gain it in a different way, by following through in the exercises I will give you later in this book; for these will enable you to extend your perceptions to these other layers of reality if you are persistent, expectant, and determined.

"It" refers to "faith in life after death".
