Like all things, the more you study and practice the better results you will get. In the initial stages the more complex and deeper teachings are best avoided, after all if you were beginning Karate you wouldn't want to be full contact sparring with a black belt on your first lesson would you? The effects of getting ahead of yourself can be detrimental and lead to confusion and frustration. If you want to start learning about Buddhism then try to be humble and start at the beginning with the eight fold path and the four noble truths. Simply apply these ethics to your life and meditated on them, you will soon start to see the benefits. Try meditating alone or with a group and don't push yourself too hard or expect too much, it can be very challenging at first. You just need to practice quietening the mind at first, that is all.
