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

It is said that the heart is in the microcosm just as the orb of the sun in the macrocosm. The mind in Sahasrara is like the disc of the moon.

If you observe awareness steadily, this awareness itself becomes the Guru that will reveal the Truth.

Concentration is not thinking of one thing. On the contrary, it is excluding all thoughts, since all thoughts obstruct the sense of one's true being. All efforts are to be directed simply to removing the veil of ignorance. Concentrating the mind solely on the Self will lead to happiness or bliss. Drawing in the thoughts, restraining them and preventing them from straying outwards is called detachment (vairagya). Fixing them in the Self is spiritual practice (sadhana). Concentrating on the heart is the same as concentrating on the Self. Heart is another name for Self.

Unless one is happy, one cannot bestow happiness on others.

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.

Suffering is the way for Realization of God.
