We are afraid of pain and desire, happiness and ease. Such an attitude is the result of desires. We call the fulfilment of desires happiness and their non-fulfilment misery. If things turn out according to our desires then there is pleasure, otherwise there is sorrow. We want to cling to happiness, which kicks us and then we cry.
Therefore, do not treat the entire life as being full of roses or as a uniform flow. Wise men have treated life as a play. Those who are detached treat it as a dream. Devotees treat it as a play of the Lord. Remember further that he who changes himself with the changing pattern of life will laugh as well as cry but he who remains as a witness will remain steady. Better it is that we appraise each situation and assess each change. Here lies the beginning of yoga.
