I feel this question is very important to be addressed. Root cause of most people and their sadness is not exactly related to money,career etc. the basic need is family and happiness.Without that one feels INSECURE. Many people living abroad including me have mood swings coz we miss our family and friends and of course our motherland. Old age brings loneliness.It is because many do not have their family or friends around. It is this “ ATTACHMENT “ which brings sadness.One is scared to die alone or be lonely. Please do not confuse this attachment to love and care. Honestly,most people seek company for time pass,for the fear of being lonely,security. However, life is unpredictable! for someone like me who lived in a joine family,surrounded by friends/acquaintances and everything cut off and coming abroad..the pangs of insecurity comes now and then.A certain fear is caused and makes me seem wrong friendships,tolerate bad mouthing relatives. I am sure many are in the same boat in this world. How do one find the inner peace and be detached?
