Guidance in practical aspects of buddhism and meditation

I read a course entitled ' Meditation without exertion' which was purportedly based on Tibetan teachings and methods. It discussed methods of developing concentration and imagination leading to Samadhi. Buddhism seems to present a practical method which leads to discipline and non attachment something which is lacking, at least in my experience, in the the western traditions. I'm looking for direction to these methods and ways of applying these methods to myself and my experience. Your guidance and input will be greatly appreciated
