If that flame doesn't move at all, then one is said to have attained yoga. You can recognize such a man by merely looking at him. His eyes are wide open, with an aimless look, like the eyes of a mother bird hatching her eggs. Always try to perform your duties without desiring any result. All, without exception, perform work.
Breathing is also an activity.
There is no way of renouncing work altogether. So do your work, but surrender the result to God. The blossom drops off when the fruit appears. One doesn't have to do one's duty after the attainment of God, nor does one feel like doing it then. In the course of spiritual discipline one gets a 'love body', endowed with 'love eyes', 'love ears', and so on.
