I studied History. Studying history for history's sake is a waste of time. You're better off studying history from Wikipedia if that's what you want to do. Incorporating history with theory (yes, history has theory) will make you more well rounded. I wrote a history thesis which incorporated ideas from linguistics, psychology/sociology, and economics to understand a historical context. Such methods are interesting because you can understand the present much more deeply.
I had an understanding of what meditation was while on an acid trip. Some people who've done lsd describe a spiritual experience which they experience. I can say I had a good experience. What I felt was an experience of me and everything around me moving as one. That is to say the universe and I are connected to one another. It is an experience which is difficult to articulate, but something which one feels. This experience is largely missing in the sensory experience of everyday life.
However, one of the better parts of my experience was watching the plants. Their movement as one is what one is attempting to mimic in meditation. Plants are immensely connected to the world in a way we are not. Mimicking them is how we can connect ourselves to the same feeling. This mimicking of plants is what I feel meditation is. It is why it became easier for me to meditate after doing lsd than before as the reasoning behind it makes much more sense.
Some things which helped me understand meditation at a deeper level are:
* Bhagavad Gita - The last couple of chapters make more sense. The whole I am everything was a bit annoying before, but it makes more sense when you get the point. If everything is One, then everything is beautiful.
* Foucault's The Subject and Power or anything Foucault - Meditation is supposed to break the chains our desire. Foucault's The Subject and Power is immensely powerful in understanding that we are all part of a system and governed by rules. Humans are by no means free but are held together by a discursive power which we are unaware of. One of the things we are supposed to realize is how we are entrapped by these rules and gain the ability to break rules.
If you think this is all tripe please feel free to ignore it. This is after all my own experience and it can be completely different to a different individual.
