I like reading different "scriptures" finding mostly the same wisdom expressed in different ways. I've read the Dhammapada, the Tao Te Ching and I just recently finished reading the Bhagavad Gita. The Bhagavad Gita is an ancient Hindu writing. Mythically, it's a dialog between a warrior (Arjuna) about to enter battle and God (Krishna) incarnated as Arjuna's friend and companion. The translation I read by Eknath Easwaran was fantastic. Click here for a link to the Amazon page: The Bhagavad Gita. He took about 70 pages just to introduce the scriptures so you would have an underestanding of the context and the terminology which can get a bit technical. Each chapter is preceded by an introduction that tells you what you are about to read.
The scriptures themselves are profound in my opinion. The advice that Krishna gives Arjuna is about the spiritual path to enlightenment. He pretty much recommends a middle path, not one of ascetism or of non-action but one of right action and devotion. If I had to say one thing that I got out of it that stood out more than any others was doing right just for the sake of doing right. Non-attachment to results is the goal. I won't attempt to sum up the scriptures themselves because I know I could not do them justice. But, if you are interested in the Bhagavad Gita, I cannot imagine there being a much better translation.
