These are phases that come in every seekers life because there are many parts and aspects in us. That is why taking to spiritual life too early especially during adolescence is not very desirable as the challenges are many. It is only when we have gone through the experiences of life keeping the right attitude that we become ready for the plunge. Until then one should read spiritual books, scriptures but also try to study well, meet the various challenges such as of job and relationship while practicing equanimity. Then after the ups and downs the flame of aspiration can be steady and the progress be uninterrupted. It takes long, many years of inner purification until the aspiration can stay longer. One has to have great patience and perseverance to go through the spiritual life until the end. After all it is the greatest adventure and the most challenging discovery of all times.
