I would like to come back to a couple of reading recommendations I used to have in my sig, while adding a bit of context. And as Goebbels knew, repetition ingrains.
(1) The Prophet by Khalil Gibran
Gives a decent idea of what life on the other side will be like.
(2) Nathan the Wise by Gotthold Ephraim Lessing
Makes a good case for how no book or tradition should divide us.
(3) Total Freedom by Jiddu Krishnamurti
As a less dense introduction I also recommend his small book on true meditation. He did a fantastic job to point out how easily spirituality can lead to delusions and nonsense. And had his finger right on how to beware such traps. How to truly stop spinning the wheel, instead of merely continuing to spin it in a more "clever" (dumber) way.
However, I must stress that he was a bit full of himself. And rather limited in his outlook. But that did provide him with much clarity. Still, his radical approach denies a lot of the magic and wonder of the ways of God. Wrongfully so. And while his decry of rituals was intelligent, rituals still can be helpful, particularly on this world. A world of illusions and lies and deceits. But yes, certainly also just as harmful.
(4) Dante's Divine Comedy
On the one hand, this is a kind of satirical slander of prominent historical figures. On the other, it plays with a genuine path. For oneself. Or a whole world. One may not exactly learn much from it. But it may, perhaps, illustrate the urgency of a path or help to get a feel for certain things.
(5) God speaks by Meher Baba
A legit Avatar of God. A second Jesus, in a way. And someone I consider to be my better. But not something I inspire to be. For I am perfectly fine, just the way I am. And I am no Jesus. And he had the luxury of being a romantic. I don't.
