A mind of gain and loss
Those who are anxious cannot reach samadhi nor attain enlightenment; their worry and impatience drives them to continually compare themselves with others, which in turn generates a mind of gain and loss. You should not compare yourself with others nor with great practitioners of the past.
Do not measure your past gains and losses against your present situation. Practice simply for the sake of practice and accept circumstances as they arise. Realize your mistakes and go forward; make up your mind to apply your method to your daily life.
Be vigorous and hard working, but let go of your anxiety.
