God..... give me that state of mind in which I shall not want anything from anybody and not even from You. 

~ Ramesh BalsekharBy its very nature it [the world] is painful and transient. See it as it is and divest yourself of all desire and fear. When the world does not hold and bind you, it becomes an abode of joy and beauty. You can be happy in the world only when you are free of it.

~ Sri Nisargadatta Maharaj

...from 'I Am That', chapter 97 - 'Mind and the World are not Separate'

It has been said that the highest wisdom lies in detachment, or, in words of Chuang-tzu: 'The perfect man employs his mind as a mirror; it grasps nothing; it refuses nothing; it receives, but does not keep.'

In short, it is to be detached from both past and future and to live in the eternal NOW. For in truth neither past nor future have any existence apart from this NOW; by themselves they are illusions. Life exists only at this very moment, and in this moment it is infinite and eternal. For the present moment is infinitely small; before we can measure it, it has gone, and yet it persists for ever.

~ Alan Watts
