Once you have completed the course of instruction in TM you will have learned a skill, a personal practice, something that you can do at home for yourself by yourself for 20 minutes twice each day, and enjoy the benefits.
Included in the course fee that you pay to learn is six months of follow-up where you will have the option to stay in contact with your teacher for regular ‘checking sessions’ in order to make sure that you are enjoying the practice, are finding it easy to fit in, and are deriving the benefits.
The study of consciousness (both experiential and intellectual) is a fascinating journey, and having learned TM there is a range of further courses such as weekend retreats and other courses which are open to you. Some people like to take their interest further, and some don’t. It’s entirely up to you.
