Be ever mindful of the shortcomings of desire’s rewards, and know that all the phenomena of the cycle of existence are never still, like the ripples on a pond, and that these manifestations of delusion, which are no things in themselves, are like magic and dreams. When you have the determination to be free of Samsara and are content with your material situation, you will be able to sit quietly with your mind happy and at ease. Kalu Rinpoche (from the book "Writings Of Kalu Rinpoche" ISBN: B000NZOA6C - http://amzn.to/16gz1CY translated by Ken McLeod.)
