Meditation is a continual concentration of thought on one idea. With regular practice, you will develop cheerfulness and inner calmness.
We offer quite a few books on the subject. The write-ups will help you decided if the book is suitable for a beginner or the experienced meditatior.
Keep in mind that there is no single method to practice. It depends on your nature and where you are spiritually. For guidence, we suggest a competent teacher.
