“Your duty is to be and not to be this or that. 'I am that I am' sums up the whole truth. The method is summed up in the words 'Be still'. What does stillness mean? It means destroy yourself. Because any form or shape is the cause for trouble. Give up the notion that 'I am so and so'. All that is required to realize the Self is to be still. What can be easier than that?”
― Ramana Maharshi

“As you watch your mind, you discover your self as the watcher. When you stand motionless, only watching, you discover your self as the light behind the watcher. The source of light is dark, unknown is the source of knowledge. That source alone is. Go back to that source and abide there.
"I Am That" - pg 188”
― Nisargadatta Maharaj

“There is no such thing as a person. There are only restrictions and limitations. The sum total of these defines the person. You think you know yourself when you know what you are. But you never know who you are. The person merely appears to be, like the space within the pot appears to have the shape and volume and smell of the pot. See that you are not what you believe yourself to be. Fight with all the strength at your disposal against the idea that you are nameable and describable. You are not. Refuse to think of yourself in terms of this or that. There is no other way out of misery, which you have created for yourself through blind acceptance without investigation. Suffering is a call for enquiry, all pain needs investigation. Don’t be too lazy to think.”
― Sri Nisargadatta Maharaj

“Be sincere in your thoughts,
Be pure in your feelings.
You will not have to run after happiness.
Happiness will run after you.”
