Hi all
I highly recommend a thorough study of Spiritual Science as put forward By Rudolph Stiener.
Read in this order:
1) Theosophy
2) Occult Science
3) Knowledge of The Spirtual Realms and its Attainment.
Once you have read those there are numerous lecture courses available. Very importantly read the lecture notes on the four Gospels as well as "The Fifth Gospel" All Free !!! All Online:

This is unsensational spiritual science.
Peace.
