The degree of freedom from unwanted thoughts and the degree of concentration on a single thought are the measures to gauge spiritual progress.

Happiness is your real nature. You identify with yourself with the body and mind, feel it's limitations, and suffer. Realize your true self in order to open the store of happiness. That true self is the reality, the Supreme Truth, which is the self of all the world you now see, the self of all the selves, the One real, the Supreme, the Eternal self - as distinct from the ego or the bodily idea for the self.

The greatest obstacle to enlightenment is getting past your delusion that you are not already enlightened.

Reality is simply the loss of ego. Destroy the ego by seeking its identity. Because the ego is no entity it will automatically vanish and reality will shine forth by itself.

There is neither creation nor destruction, neither destiny nor free will, neither path nor achievement. This is the final truth.

See what helps you to keep away all other thoughts and adopt that method for your meditation.

Because truth is exceedingly subtle and serene, the bliss of the Self can manifest only in a mind rendered subtle and steady by assiduous meditation.
