When we want an advanced education or advanced degree in any subject, we admit ourselves to a school or several schools, but we never forget the main subject that we are going to obtain advanced degree in. Thus, we may obtain Master’s or Doctorate degree in Physics, but we may need to do subsidiary courses such as Mathematics, English, History, etc. But, we never forget that we are a student of Physics during all the courses.
Similarly, the one who wants to advance in Yoga has to know that amongst all experiences or learning in the life situations, Yoga is their main subject. Only such a person really advances in Yoga. Others get carried away by nature, caves, mystical places, beautiful lakes, farms, and several other things.
