Question: You instruct to have the mind concentrated without any resolutions. Can one make the mind concentrated without using resolutions?
Yes definitely. At the initiation we tell, "Do not imagine." The mind normally has hundreds, thousands of thoughts. When we meditate the thoughts and visions come up because when the mind becomes concentrated and is applied on the brain, the mind's impressions get decodified.
So Krishna says, "You are your own best friend or your own worst enemy." The meaning is that if the mind is controlled, then it is your best friend; but if the mind is out of control you will be dancing to the brain's reflections.
So the instruction for meditation is given, "Do not think." Then the mind gets concentrated and it becomes introverted and goes towards the Self.
