Joy and grief are as day and night; they have to be put up with and gone through. They will neither appear nor disappear at your will! Both are related to the physical or the material - the body; they do not affect the soul. You are liberated the moment you transcend joy and grief. What is there to grieve in life? Did you grieve when your body underwent changes? The child disappears in the boy, the boy in the youth, the youth is lost in the middle-aged man who in turn is lost in the old man. You never weep over these changes that affect the body; why then, when the body is lost in death? Whatever changes your body may suffer, the Atma, the splendour of the true Wisdom remains immortal. Being established unshakably in this knowledge is the sign of the wise, the Jnani.( Geetha Vahini, Ch 1)
