Jayapataka Swami: The anarthas are such that, we have some days very good, strong, some days not so good, not so strong,that means unsteady,and then niṣṭhā means you are steady. So, when you actually become almost free from the anarthas, you become more fixed, more steady in practicing devotional service. There may be minor anarthas, but as they decrease, your nista increases.
