Swami Mukundananda
Why do my feelings keep going up and down, even in devotion?
Feelings ride a roller coaster because the mind makes them
Feelings go up and down because they are created by the mind. If you don't take charge of your mind, the mind will become your worst enemy.
So, they are riding the waves of their feelings. Now, the feelings are on a roller coaster because they are created by the mind. And if you don't take charge of your mind, the mind will become your worst enemy.
