First of all, apologies for the title. I've spent awhile trying to figure out what to type here and that was the best I could figure out.
For those that aren't up to speed.
I've been a Buddhist for about 10 years. About 4 years ago or so I found a teacher in the Dudjom Tersar lineage and started practicing Ngondro after being given the teaching(once by one of the lamas working under him and once by him as part of a group class). I have been practicing Ngondro at varying levels of intensity since then(including all of the visualizations that my teacher requested that we do).
The main things that happened during this time was that I was involved in a very traumatizing and isolating relationship and was in therapy and medication on and off for clinical depression. This will become important later in the story.
As I practiced I realized I had very serious doubts about not just the Dharma but about everything. As someone who is at his core a very serious agnostic(I don't believe that we can be certain about anything in reality at all, even the absence of certainty) this isn't very unusual. What was new was that I realized the consequences of these doubts, especially in regards to what happens after we die.
As it stands we don't have a way to say that the Islamic, atheist, fundamentalist Christian, Buddhist or Hindu afterlife is what actually happens or how we get to a specific one if our actions determine where we go.
And since what you are supposed to do for all of them(be a good Muslim, nothing, get straight with Jesus, work towards Enlightenment, and worship God in a specific way) either don't agree or in some cases contradict each other it is pretty important to figure out either which experience happens to everyone or the mechanism by which it is determined what happens to people.
Now, of course, many people would say, "Well, if you practice then certainty will come." Here is the problem I've run into with that. Part of being diagnosed with depression is that, by definition, you can't trust your own mind. Because of this you have to verify everything via external methods, otherwise you might think that jumping off of a bridge is a revealed insight and be dead before lunch(not that I've had thoughts like that for a couple of years).
Another thing that has been worrying me is the difference between Enlightenment and happiness. When I originally started I thought that Enlightenment was the same as happiness. Though there might be some rough patches the path to Enlightenment seemed to be one that would lead to greater and greater happiness over time. I have not found this to be the case at all. Practice has made my life harder, not easier. When I practice I am reminded that I don't know with any certainty what happens when I die, that the primary method everyone says I have to use to verify this(internal experience) I can't trust, and that Enlightenment is(to me, at least) not logically understandable(and thus something to view with great skepticism). It's like when a dog pees on the carpet and you rub his nose in it to get him to stop.
Now, I told my teacher a very abbreviated version of this and his response was, "Do Vajrasattva instead of prostrations" which I have done. And it has produced precisely 0 change. I still don't know what Enlightenment is, I still don't know what happens when we die, and I still can't trust my inner experiences at all if they aren't vetted by rigorous standards. On the other hand, I have noticed that getting a new significant other, exercising, eating right, staying away from "doomer" media, taking St. John's Wort, and socializing with people has helped with my depression immensely. However, according to how I understand Buddhism that should not be the case at all. Practice should make things better and anything else should make things worse.
I'm not sure what I'm asking for precisely, here. Maybe this is just for me to be able to look at my own thoughts.
