Atttachment

Buddha has said, and so has Krishna that attachment is the cause of all sorrows, and if a person wants to live a happy life, he must learn to be detatched.Many years ago when our son was under treatment for a heart ailment and we used to find ourselves absolutely helpless, I often used to wonder that is it really possible for  a person to be detached from what is happening to his world. I have realized over the years that although a person may cultivate a degree of detachedness towards the material aspects of life , and I feel that I have been able to do so to  a great extent,yet doing the same towards those whom you love is next to impossible. It is like one of those advices that are so impractical. If it were so easy to be detached towards your kith and kin, won't you attain Nirvana?
