Premanand Maharaj Ji
What should I do when my mind will not settle in bhajan because of tamas and laziness?
Sing loudly to break tamas
Tamas (the dulling quality) brings sleep, laziness and dullness, so the mind sticks neither in worldly pleasure nor bhajan. Keep up the Name and loud singing whether or not feeling arises.
Saying Radha Radha, if the mind is not in bhajan, fine, we sing Chaurasi Ji.
