One of the most well recognised non-dual mystics in modern time: Nisargadatta Maharaj. He was very intelligent and articulate – one of my favourites.
*The mind covers up reality, without knowing it. To know the nature of the mind, you need intelligence, the capacity to look at the mind in silent and dispassionate awareness.
*This attitude of silent observation is the very foundation of yoga. You see the picture, but you are not the picture.
*Love says “I am everything”. Wisdom says “I am nothing”. Between the two, my life flows. Since at any point of time and space I can be both the subject and the object of experience, I express it by saying that I am both, and neither, and beyond both.
*Once you accept time and space as real, you will consider yourself minute and short-lived. But are they real? Do they depend on you, or you on them? As body, you are in space. As mind, you are in time. But are you mere body with a mind in it? Have you ever investigated?
