Every living being longs always to be happy, untainted by sorrow; and everyone has the greatest love for himself, which is solely due to the fact that happiness is his real nature. Hence, in order to realize that inherent and untainted happiness, which indeed he daily experiences when the mind is subdued in deep sleep, it is essential that he should know himself. For obtaining such knowledge the inquiry 'Who am I?' in quest of the Self is the best means.

If one's mind has peace, the whole world will appear peaceful.

You may go on reading any number of books on Meditation. They can only tell you ‘Realize the Self’. The Self cannot be found in books. You have to find it for yourself in yourself.

Self-inquiry is the process and the goal also. 'I am' is the goal and the final reality. To hold to it with effort is self-inquiry. When spontaneous and natural it is realization.

The Sage has no thinking mind and therefore there are no ‘others’ for him.

Peace is your natural state. It is the mind that obstructs the natural state.

It is within your competence to think and thus to get bound or to cease thinking and thus be free.
