How is dhyana practised - with eyes open or closed? Ramana Maharshi.: It may be done either way. The point is that the mind must be introverted and kept active in its pursuit. Sometimes it happens that when the eyes are closed the latent thoughts rush forth with great vigour. It may also be difficult to introvert the mind with the eyes open. It requires strength of mind to do so. The mind is contaminated when it takes in objects. Otherwise, it is pure. The main factor in dhyana is to keep the mind active in its own pursuit without taking in external impressions or thinking of other matters.
