The second stage of anisthita bhakti is called ghana-tarala, which literally means “thick-thin” or sporadic endeavor. Sometimes we are enthusiastic and think, “I feel good about my practice of bhakti. I am getting the respect I deserve and the results I am earning. Everything is going so nicely.” But then things change: “This consciousness is too difficult. I have no taste, and no one respects me.” We lose our enthusiasm. Sometimes when we lose our enthusiasm, we also lose our ability to practice regulated sadhana. We get absorbed in material consciousness, then begin to suffer, and take up the chanting again. We gain a little steadiness, then stop again, because we have not discovered the importance of chanting or the truth about ourselves.
