When we identify ourselves with our body, it is actually incorrect. We are pure consciousness and we know this only through knowledge. We take many births, and bodies go on changing in every birth but we are the same, untouched by death, though bodies died. Similar is the story with mind. It is always changing with all sorts of thoughts. In this way, only we are aware of these changes happening. We are witness to these. But experience has to be there. Our body is mortal. In our being aware of ourselves, there is immense joy and not pain or suffering. Our self knows pure existence and truth. Only with experience we can get bliss. When we realize that our mind is in our body, but it is not our self and is different from our self, then only we will not have pain, suffering, jealousy and hatred in our mind. We should be detached, then only we can really enjoy. Change is the nature of mind and also of the whole world and so change will happen. We should realize that nothing will happen to us, and we will be the same.
