How can an unsteady mind make itself steady? Of course it cannot. It is the nature of the mind to roam about. All you can do is to shift the focus of consciousness beyond the mind.
Sri Nisargadatta MaharajContemplate life as infinite, undivided, ever present, ever active, until you realize yourself as one with it. It is not even very difficult, for you will be returning only to your own natural condition.
