Congrats on your new journey, brother!!
For one thing, do away with ALL the notions about religion, GOD, and the like that you have had thus far. Or at least set them aside. Resist the urge to compare ATR's with the 3 major religions. You have to remember, that the latters came from the formers, and not vice versa.
Also, clear your mind on a personal level, when beginning to study. Leave all the issues that you went through today behind.
It would help if you are beginning to clean up your diet, if you haven't done so already. That's going to be very important along the way.
And NEVER be afraid to ask questions, from those of us who have knowledge on on this subject. Wise council is always beneficial.
May you be at PEACE, and let us know how things turn out.....There are others here who are in the same boat as you are (as a neophyte), and I'm sure that they will benefit from you sharing your new experiences.
