Gratitude, that is very important.
The Bhakti that arises out of this gratitude – gratitude to Him who has directed us into this most remarkable advaita -- raises its head now and then. Of course we may have to maintain it for a very short time and quickly resume our journey.
However, this Bhakti of short duration is so intense that all that bhakti that we did long ago for the one-pointedness of the mind pales into insignificance.
When we were carrying on that Bhakti almost incessantly, it was like a routine, and sometime lifeless.
But now on our jnAna path, a certain bhakti shoots forth as if from an underground spring, along with a sense of gratitude, and even though it is only for a moment, it is full of life.
But since our objective is nirguNa, even from this, the mind has to be turned off.
