You are awareness. Awareness is another name for you. Since you are awareness there is no need to attain or cultivate it. All that you have to do is to give up being aware of other things, that is of the not-Self. If one gives up being aware of them then pure awareness alone remains, and that is the Self.

Concentration of the mind is in a way common to both Knowledge and Yoga. Yoga aims at union of the individual with the universal, the Reality. This Reality cannot be new. It must exist even now, and it does exist.

If there is anything besides the Self there is reason to fear? Who sees the second? First, the ego arises and sees objects as external. If the ego does not rise, the Self alone exists and there is no second.

There must be a subject to know the good and evil. Thatsubject is the ego.

The pure mind is itself Brahman; it therefore follows that Brahman is not other than the mind of the sage.

Calmness is the criterion of spiritual progress. Plunge the purified mind into the Heart. Then the work is over.

Till you reach the state of jnana and thus wake out of maya you must do social service by relieving suffering whenever you see it. But even then you must do it without ahankara, i.e., without the sense of 'I am the doer', but with the feeling 'I am the Lord's tool'.
