Premanand Maharaj Ji
How do I avoid dozing off during satsang?
Sit in asan with open eyes
Sit in asan (a steady seated posture) with a steady gaze on the speaker or the tip of the nose. Do not listen with eyes closed, since sleep and laziness can come.
With eyes closed, sleep can come, and laziness. So keep the gaze on the nose tip or fixed on the speaker.
